Applications
S+M offers a broad range of NTC thermistors for temperature measurement and inrush currentlimiting. To facilitate selection of the right thermistor for your application we have compiled thefollowing tables and charts.
Temperature measurement
Temperatures can be determined by point-matching or uni curve NTC thermistors. While point-matching thermistors feature their highest accuracy in a tight range around the rated temperature,uni curve thermistors exhibit a high measuring accuracy over a wide temperature range.
The chart for point-matching thermistors on page 20 assigns the different models and their ratedresistances RN to rated temperatures TN.
With the table below you can select uni curve thermistors by resistance ratings (at 25 °C) and tem-perature tolerances .
Uni curve NTC thermistors
Inrush current limiting
NTC thermistors can limit excessive inrush currents effectively and at attrative cost. Fields of appli-cation are electric motors, transformers and switch-mode power supplies. The chart on page 22correlates sizes, maximum permissible currents Imax and typical NTC resistances R25.

General Technical Information
1 Definition
As defined by IEC 539, CECC 43 000 and DIN 44 070, NTC (Negative Temperature Coefficient)thermistors are thermally sensitive semiconductor resistors which show a decrease in resistance astemperature increases. With – 2%/K to – 6 %/K, the negative temperature coefficients of resistanceare about ten times greater than those of metals.
Changes in the resistance of the NTC thermistor can be brought about either externally by a changein ambient temperature or internally by self-heating resulting from a current flowing through the de-vice. All practical applications are based on this behavior.
NTC thermistors are made of polycrystalline mixed oxide ceramics. The conduction mechanisms inthis material are quite complex, i.e. either extrinsic or intrinsic conduction may occur. In many casesNTC thermistors have a spinell structure and then show valence conduction effects.
2 Manufacture
S + M thermistors are produced from carefully selected and tested raw materials. The starting ma-terials are different oxides of metals such as manganese, iron, cobalt, nickel, copper and zinc, towhich chemically stabilizing oxides may be added to achieve better reproducibility and stability ofthe thermistor characteristics.
The oxides are milled to a powdery mass, mixed with a plastic binder and then compressed into thedesired shape. Standard shapes are:
Disks: The thermistor material is compressed under very high pressure on pelleting machines toproduce round, flat pieces.
Wafers: The ceramic material is compression-molded or drawn and then cut to the required shape.
Beads: The oxide/binder mixture is deposited in the form of small ellipsoids on two fine parallelwires made of platinum alloy.
The blanks are then sintered at high temperatures (between 1000 and 1400 °C) to produce the poly-crystalline thermistor body. Disks are contacted by baking a silver paste onto the flat surfaces. Withbeads the wires embedded in the sintered body serve as contacts. Depending on the application,the thermistors are fitted with leads or tab connectors, coated or additionally incorporated in differ-ent kinds of housing. Finally the thermistors are subjected to a special ageing process to ensurehigh stability of the electrical values. Otherwise the NTC resistance would possibly change even atroom temperature due to solid-state reactions in the polycrystalline material.
A flow chart in the quality section of this book (see page 145) shows the individual processing stepsin detail. The chart also illustrates the extensive quality assurance measures taken during manu-facture to guarantee the constantly high quality level of our thermistors.
3 Characteristics
A current flowing through a thermistor may cause sufficient heating to raise the thermistor’s temper-ature above the ambient. As the effects of self-heating are not always negligible (or may even beintended), a distinction has to be made between the characteristics of an electrically loaded ther-mistor and those of an unloaded thermistor. The properties of an unloaded thermistor are alsotermed “zero-power characteristics”.

General Technical Information
3.2.6 Thermal cooling time constant τc
The thermal cooling time constant refers to the time necessary for an unloaded thermistor to varyits temperature by 63,2% of the difference between its mean temperature and the ambient temper-ature.
τc depends to a large extent on the component design. The values of τc specified in this data bookhave been determined in still air at an ambient temperature of 25 °C.
The NTC thermistor is internally heated to 85 °C to measure subsequently the time it requires tocool down to 47,1 °C at an ambient temperature of 25 °C. This adjustment to the ambient is asymp-totic and occurs all the faster, the smaller the device is.
3.2.7 Thermal time constant τa
The thermal time constant refers to the time it takes an unloaded thermistor to raise its body tem-perature from 25 °C to 62,9 °C when it is immersed in a medium having a temperature of 85 °C.Equally to thermal cooling time constant, τa depends on the medium surrounding the device. Themedium used for measuring τa (e.g. water) is specified in the data sheets.
Determining the thermal time constant:
a) The zero-power-resistance is measured at 25 °C.The zero-power resistance is measured at 62,9 °C.
b) The NTC thermistor is immersed in a liquid bath with a temperature of (25 ± 0,1)°C until it hasassumed the same temperature as the liquid.
c) The NTC thermistor is then immediately transferred into a second bath with a temperature of(85 ± 0,1)°C. Subsequently the time is measured it takes the thermistor to reach again the zero-power resistance measured under a) for 62,9 °C.
The resulting time is the thermal time constant for an external temperature change.
3.2.8 Ageing and stability
At room temperature the polycrystalline material NTC thermistors are made of shows solid-state re-actions which lead to an irreversible change in the characteristics (usually resistance increase,change of B value etc).
Physical reasons for this may be thermal stress causing a change in concentration of lattice imper-fections, oxygen exchange with the environment (with unprotected, non-glass-encapsulated ther-mistors) or diffusion in the contact areas of metallized surface contacts. At low temperatures thesereactions slow down, but at high temperatures they accelerate and finally decline with time. Toenhance long-term stability, our NTC thermistors are subjected to an ageing process directly aftermanufacture.

4 Application notes
4.1 Applications utilizing the influence of ambient temperature on resistance(self-heating negligible!)
4.1.1 Temperature measurement
The high sensitivity of an NTC thermistor makes it an ideal candidate for temperature sensingapplications. These low-cost NTC sensors are usually employed for a temperature range of – 40to + 300 °C.
Selection criteria for NTC thermistors are– temperature range– resistance range– measuring accuracy– environment (surrounding medium)– response time– dimensional requirements.
One of the circuits suitable for temperature measurement is a Wheatstone bridge with an NTCthermistor used as one bridge leg.
With the bridge being balanced, any change in temperature will cause a resistance change in thethermistor and a significant current will flow through the ammeter. It is also possible to use a variableresistor R3 and to derive the temperature from its resistance value (in balanced condition).
4.1.2 Linearizing the R/T characteristic
NTC thermistors exhibit a distinctly non-linear R/T characteristic. If a fairly linear curve is requiredfor measurements over a (wide) temperature range, e.g. for a scale, series-connected or paralleledresistors are quite useful. The temperature range to be covered should, however, not exceed 50to 100 K.

General Technical Information
It is important to match the temperature of the compensating NTC thermistor to that of the compo-nent causing the temperature response. Temperature-compensating thermistors are therefore notonly available in conventional leaded styles, but also incorporated in screw-type housings for at-tachment to heat sinks and as chip version for surface mounting.
Figure 8 shows a simple circuit configuration for a thermostat.
NTC thermistors for temperature measurment are suitable for a large variety of applications
in household electronics: in refrigerators and deep freezers, washing machines, electric cookers,hair-driers, etc.
in automotive electronics: for measuring the temperature of cooling water or oil, for monitoringthe temperature of exhaust gas, cylinder head or braking system, for controlling the temperaturein the passenger compartment, …
in heating and air conditioning: in heating cost distributors, for room temperature monitoring, inunderfloor heating and gas boilers, for determining exhaust gas or burner temperature, as out-door temperature sensors, …
in industrial electronics: for temperature stabilization of laser diodes and photoelements, for tem-perature compensation in copper coils or reference point compensation in thermoelements, etc.
4.2 Applications utilizing the non-linear voltage/current characteristic (in self-heated mode)
4.2.1 Inrush current limiting
Many items of equipment like switch-mode power supplies, electric motors or transformers exhibitexcessive inrush currents when they are turned on, meaning that other components may be dam-aged or fuses may be tripped. With NTC thermistors it is possible to effectively limit these currents,at attractive cost, by connecting a thermistor in series with the load.
The NTC thermistors specially developed for this application limit the current at turn-on by their rel-atively high cold resistance. As a result of the current load the thermistor heats up and reduces itsresistance by a factor of 10 to 50; the power it draws reduces accordingly.
Figure 8

Relay
Siemens Matsushita Components 35
General Technical Information
NTC thermistors are able to effectively handle higher inrush currents than fixed resistors with thesame power consumption.
The NTC thermistor thus provides protection from undesirably high inrush currents, while its resis-tance remains negligibly low during continuous operation.
4.2.2 Series and parallel connection
An NTC thermistor is always connected in series with the load to be protected. If the inrush current can-not be handled by one thermistor alone, two or more thermistor elements can be connected in series.
Paralleling several NTC thermistors is inadmissible, since the load will not be evenly distributed.The thermistor carrying the largest portion of current will heat up until it finally receives the entirecurrent (which may result in destruction of the device), while the other paralleled thermistors remaincold.

General Technical Information
Figure 11 shows a typical example of an inrush protection circuit:
Figure 11
Mounting positions for NTC thermistors in a protective circuit
Selection of the most appropriate NTC thermistor is the precondition for effective circuit protection.The first and most important criterion is the maximum current during continuous operation, which isdetermined by the load. The rated resistance of the thermistor results from this current value.
4.2.3 Self-heating
The self-heating of a thermistor during operation depends on the load applied. Although some heatis being dissipated, the NTC thermistor may in extreme cases reach a mean temperature of up to250 °C. The dissipation factor δth specified in the data sheets has been measured in still air atTA = 25 °C on devices with clamp contacts. A change in the measuring conditions (e.g. stirred air =blower increases the dissipation factor ) will influence the dissipation factor.
The heat developed during operation will also be dissipated through the lead wires. When mountingNTC thermistors it should therefore be considered that the contact areas may become quite hot atmaximum load.

General Technical Information
4.2.4 Load derating
The power handling capability of an NTC thermistor cannot be fully utilized over the entire temper-ature range. For circuit dimensioning the derating curve given below provides information on theextent to which the current must be reduced at a certain ambient temperature.
Figure 12
Derating curve
The Imax values specified in the data sheets denote the maximum permissible continuous current(dc or rms values for sine-shaped ac) in the temperature range 0 °C to 65 °C.
4.2.5 Restart
When the load has been switched off the thermistor slowly cools down. Its resistance increasessteadily, but the full resistance value is only reached after 1 to 2 minutes (depending on ambienttemperature and type).
It may therefore be useful in some applications to bypass the thermistor during restart. Operationcan thus be faster resumed and system performance will not be affected by the thermistor.
4.2.6 Dependence of NTC resistance on current
The resistance effective in the usual current range can be approximated as follows:

The calculated values only serve as an estimate for operation in still air at an ambient temperatureof 25 °C.
Note: With the equation above sufficiently accurate results are only obtained for the limited currentrange stated above.
4.2.7 Pulse strength
The currents during turn-on are much higher than the rated currents during continuous operation.To test the effects of these current surges S+M uses the following standard procedure:

In the pulse test the capacitor CT is discharged via the series resistor RS and the NTC thermistor.The load voltage is chosen such that the voltage applied to the thermistor at the start of dischargeis VNTC = 345 V (corresponds to (230 V + ∆V ) × ).

4.3 Applications utilizing the influence of the disspation factor on the voltage/current characteristic
4.3.1 Liquid level sensors
The temperature of an electrically loaded NTC thermistor depends on the medium surrounding thedevice. When the thermistor is immersed in a liquid the dissipation factor increases, the temperaturedecreases and the voltage lying across the NTC rises. Owing to this effect NTC thermistors are ableto sense the presence or absence of a liquid.
Glass-encapsulated beads are particularly suitable for level sensing. On the one hand the glasscoat protects the thermistor from the liquid to be monitored, and on the other hand it is thin enoughto ensure good thermal contact.
Examples of suitable types: K17, M85.

General Technical Information
4.3.2 Flow rate and vacuum measurement
Here too, the thermistor is operated by means of an electrical load. Its temperature and resistanceare influenced by the surrounding medium. Stirred air lowers the NTC’s temperature and thus in-creases its resistance. A vacuum, in contrast, increases the NTC’s temperature and thus causes adecrease in resistance. Hence NTC thermistors can be used to monitor ventilators, to measure theflow rate of gases or for vacuum measurement.
Examples of suitable types K17, K19.

e of a relay delayed by a thermistor depends on the recovery time of the ther-has to cool down before it can cause second delay. If the thermistor remains 3 · τth (3 times the thermal cooling time constant) between two operations, delay will be 80 % to 90 % of that for the first delay. It is therefore useful toff the thermistor by additional relay contacts, so that the thermistor has suf-n (see dashed section in figure 17).

Small in size, big in performance
Our selection of capacitors rangesfrom standard sizes down to a mini-ature highlight in 0402 style. Mea-suring only 1 x 0.5 x 0.5 mm, it’s anideal solution for applications wherespace is tight, like in handies andcardiac pacemakers. At the sametime all our chips can boast excellentsoldering characteristics, with specialterminal variants for conductive ad-hesion. And we also thought aboutthe right packing for automatic place-ment. You get all sizes down to 1206in bulk case for example, plus voltageratings from 16 to 500 V. By the way,our leaded models have CECCapproval of course, in fact theywere certified more than tenyears ago.

Mounting Instructions
1 Soldering
1.1 Leaded NTC thermistors
Leaded thermistors comply with the solderability requirements specified by CECC.
When soldering, care must be taken that the NTC thermistors are not damaged by excessive heat.The following maximum temperatures, maximum time spans and minimum distances have to beobserved:
Dip soldering Iron soldering
Bath temperature max. 260 °C max. 360 °CSoldering time max. 4 s max. 2 sDistance from thermistor min. 6 mm min. 6 mm
Under more severe soldering conditions the resistance may change.
1.2 Leadless NTC thermistors
In case of NTC thermistors without leads, soldering is restricted to devices which are provided witha solderable metallization. The temperature shock caused by the application of hot solder may pro-duce fine cracks in the ceramic, resulting in changes in resistance.
To prevent leaching of the metallization, solder with silver additives or with a low tin content shouldbe used. In addition, soldering methods should be employed which permit short soldering times.
1.3 SMD NTC thermistors
The notes on soldering leadless thermistors also apply to the SMD versions (see IEC 68-2-58).
1.3.1 Wettability test in accordance with IEC 68-2-58

1.3.4 Notes
Iron soldering should be avoided, hot air methods are recommended for repair purposes.
2 Conductive adhesion
An alternative to soldering is the gluing of thermistors with conductive adhesives. The benefit of thismethod is that it involves no thermal stress. The adhesives used must be chemically inert.
3 Clamp contacting
Pressure contacting by means of clamps is particularly suitable for applications involving frequentswitching and high turn-on powers.
4 Robustness of terminations
The leads meet the requirements of IEC 68-2-21. They may not be bent closer than 4 mm from thesolder joint on the thermistor body or from the point at which they leave the feed-throughs. Duringbending, any mechanical stress at the outlet of the leads must be removed. The bending radiusshould be at least 0,75 mm.
Tensile strength: Test Ua1:Leads ∅ ≤ 0,5 mm = 5 N
∅ > 0,5 mm = 10 N
Bending strength: Test Ub:Two 90°-bends in opposite directions at a weight of 0,25 kg.
Torsional strength: Test Uc: severity 2The lead is bent by 90° at a distance of 6 to 6,5 mm from the thermistor body.The bending radius of the leads should be approx. 0,75 mm. Two torsions of180° each (severity 2).
When subjecting leads to mechanical stress, the following should be observed:
Tensile stress on leads
During mounting and operation tensile forces on the leads are to be avoided.
Bending of leads
Bending of the leads directly on the thermistor body is not permissible.
A lead may be bent at a minimum distance of twice the wire’s diameter + 2 mm from the solder jointon the thermistor body. During bending the wire must be mechanically relieved at its outlet. Thebending radius should be at least 0,75 mm.
Twisting of leads
The twisting (torsion) by 180° of a lead bent by 90° is permissible at 6 mm from the bottom of thethermistor body.

When thermistors are sealed or potted, there must be no mechanical stress through differing ther-mal expansion in the curing process and during later operation. In the curing process the upper cat-egory temperature of the thermistor must not be exceeded. It is also necessary to ensure that thepotting compound is chemically neutral.
6 Cleaning
If cleaning is necessary, mild cleaning agents such as freon, trichloroethane and perchloroethyleneare recommended. Ultrasonic cleaning methods are permissible.
7 Storage
In order to maintain their solderability, thermistors must be stored in a non-corrosive atmosphere.Humidity, temperature and container materials are critical factors.
If possible, the components should be left in the original packing. Touching the metallization of un-soldered thermistors may change their soldering properties.

2 General
S+M has set up extensive quality assurance systems in order to meet the stringent technical de-mands of an open world market. These systems follow the CECC ISO-9000 to ISO-9004 standards.Our QA system received the ISO 9001 certificate in September 1991.
3 Sequence of quality assurance measures
The quality department tested and released the thermistors described in this data book on the basisof the following criteria: compliance with type specifications, process capability of production equip-ment as well as accuracy of measuring and test methods and equipment.
To ensure a constantly high quality level, the following tests are carried out:
3.1 Incoming inspection
The parts and materials required for production are checked for dimensional accuracy and materialproperties in a prescribed sequence.
3.2 Process assurance
To achieve the objective of eliminating defects as efficiently as possible and at their very source,quite different measures are taken. Modern quality tools such as FMEA (Failure Mode and EffectAnalysis) are used already during the starting phase: A risk-priority figure is assigned to potentialdefects according to their significance as well as to the probability of occurrence and detection. Incase of high risk-priority figures, remedial measures are taken from the beginning. During produc-tion all essential processes are subject to statistical process control (SPC).
3.3 Product assurance
Each manufacturing stage is followed by a socalled “quality control gate”, i.e. the product is onlyreleased for the next stage after passing a corresponding test. The test results are constantly mon-itored and evaluated and are then used to assess the quality of the manufacturing process itself(refer to 3.2).
3.4 Final inspection
Final measurements and conformance tests ensure that delivery quality is kept constant within de-fined tolerances.
4 Delivery quality
The term delivery quality designates the conformance with agreed data at the time of delivery.

Quality
5 Sampling inspection
The customer may carry out incoming inspections which are subject to standardized sampling in-spection plans specifying the acceptance or rejection of a delivery lot in conjunction with agreedAQL values (AQL = acceptable quality level).
The scope and the maximum permissible number of defects of a sampling inspection are specifiedin IEC 410 (identical with MIL-STD 105 D and DIN ISO 2859-1), single sampling plan for normalinspection, inspection level II. The sampling instructions of this standard are such that a deliveredlot will be accepted with a high degree of probability (greater than 90 %), if the percentage of defec-tives does not exceed the specified AQL level.
Generally, the average defect percentage of our deliveries lies clearly below the AQL value. This isensured by appropriate quality assurance measures in the manufacturing plants and substantiatedby the final inspections.
6 Classification of defects
A component is considered defective if it does not comply with the specifications stated in the datasheets or in an agreed delivery specification. Defects which generally exclude the functional use ofthe component (inoperatives) are classified separately from less significant defects.
Inoperatives of thermistors are:
– Short circuit or open circuit– Component, case, terminals or encapsulation broken– Incorrect marking– Mixing of different types
Other defects are:
– Electrical defects (maximum ratings are exceeded)– Mechanical defects, e. g. incorrect dimensions, damaged housings, illegible marking, twisted
leads
7 AQL values
The following AQL values apply to the quoted defects
– for inoperatives (electrical and mechanical) 0,065– for the total number of electrical defectives 0,250– for the total number of mechanical defectives 0,250
The values for the total number of defectives include related inoperatives.

8 Incoming inspection by the customer
The quality of our products is ensured by the QA measures assigned to the individual productionstages as shown on page 145. Thus the customer can do away with cost-intensive incoming inspec-tions. If a customer wishes nevertheless to carry out an incoming inspection, we recommend thatthe inspection plan shown below is used. The inspection methods employed must in this case beagreed upon between customer and supplier. In many cases a stricter inspection method is agreedupon to the effect that the sample size corresponds to the plan, the required inspection, however,demands “zero defects”, i. e. a lot will only be accepted if the samples are free from defects. Re-gardless of that, all sample tests carried out at S+M are subject to these stricter test conditions (zerodefects).
The following information is required for the assessment of possible claims: test circuit, sample size,number of defectives found, sample defectives and packing slip, delivery note number, lot numberand/or label.

Additional condition:
As an acceptance number of 0 and a rejection number of 1 provides only limited information on theactual AQL, the next higher sample size should be taken.

9 Reliability
We conduct a large variety of endurance trials and environmental tests to assure the reliability ofPTC thermistors. These tests derive from the extremes of expected application conditions, with ex-tra tightening of the conditions so that significant results can be obtained within a reasonableamount of time.
The reliability testing programs of S + M are based on the test plans of relevant CECC standardsfor assessing the quality of electronic components. Environmental tests are conducted according toIEC 68-2 (Electrical Engineering, Basic Environmental Testing Procedures).
S + M performs reliability tests both in qualifying new component families as well as for periodicrequalification. Reliability figures for various component series can be found in the data sheets.
10 Identification and traceability
On the packaging of all shipped thermistors you will find a bar code label stating type, part number,quantity, date of manufacture and lot number. These details are necessary for speedy and informa-tive handling of returns.
This systematic and unmistakable form of identification means that each component can be tracedto a certain production lot. This in turn permits retracing back through the entire fabrication processas far as raw materials purchasing.

11 Supplementary information
The issuing of quality data – which always relate to a large number of components – is no assuranceof characteristics in a legal sense. But an agreement on such data does not exclude the customer’sright to claim replacement of individual defective NTC thermistors within the terms of delivery. Wecannot assume any further liability, especially for the consequences of component failure.
You should also remember that figures for failure rate refer to an average fabrication situation andare therefore to be understood as mean values (statistical expectations) for a large number of de-livery lots of homogeneous NTC thermistors. They are based on application experience as well ason data derived from preceding inspection under normal or – for the purpose of acceleration – tight-ened conditions.

Siemens Matsushita Components GmbH & Co. KG (S + M Components for short) is responsible forprotection of the environment in the development, fabrication and use of its products for the intend-ed purpose. S + M Components is very thorough in fulfilling the resulting obligations. Over andabove the legal prescriptions, our guiding principle here is the corporation’s responsibility towardsman and environment.
Responsibility for safety in working with materials that have a potential environmental impact is inthe hands of the various managers. This involves, in the first place, instructing and informing thestaff concerned. A specially trained environmental protection supervisor watches over adherenceto regulations, reports on the introduction of processes within an environmental context and on de-cisions relating to investment (e.g. he checks that all environmentally associated requirements likefilters and sumps have been considered). But advising and informing staff take on the highest pri-ority; this is the only way to ensure that all protective measures are known and observed.
All chemicals employed in development and fabrication are examined for environmental compati-bility or harmful effects before their use on the basis of DIN safety specifications. Alternatives aredevised if risks emerge. The result of this procedure is that today all CFCs as well as all highly toxicmaterials have been eliminated entirely from the fabrication process.
Dust and vapor generated during fabrication are filtered away for disposal. The emission figures ofthe filters are constantly examined; considerable efforts are undertaken to ensure that these figuresare well below the legally prescribed limits. The same applies to the water used in a plant. This beingcleansed in a special waste-water treatment process. Water consumption has been reduced sub-stantially in recent years through the use of cooling water circuits and water recycling.
Waste produced in the fabrication of components is sorted and collected on the spot and recycledby state-of-the-art methods.
The packaging material used for our components can be fully recycled.
All NTC thermistors can be disposed of on a dump for industrial waste that is similar to householdrefuse without any special precautions.
Of course, we are still by no means satisfied with what we have already achieved, and more stepsare due to follow in the interest of further reducing and ultimately eliminating entirely all environmen-tal impact created in the development and fabrication of our components.

1 Reliability data
For most measuring NTCs and in particular for those featuring high measuring accuracy, reliabilitydata are given in the data sheets. These data provide information on the deviation of rated resis-tance under high thermal, electrical or mechanical stress.
These resistance tolerances are in the range of a few percent and have therefore no relevance forcoarsely tolerated NTC thermistors.
2 Operating temperature range / ambient temperatures
Thermistors are assigned to climatic categories according to the climatic conditions under whichthey have been tested.
The IEC climatic category is specified for all NTC thermistors in the data sheets. In accordance withIEC 68-1 (Appendix A) the climatic category is made up of three sets of digits, which are decodedas shown in the following example:
Example:
Climatic category 55/085/56
Test C: Damp heat (duration of test)56 days(in accordance with IEC 68-2-3)
Test B: Dry heat (upper category temperature)+ 85 °C(in accordance with IEC 68-2-2)
Test A: Cold (lower category temperature)– 55 °C(in accordance with IEC 68-2-1)
