Pioneer of the original high voltage vacuum variable capacitor

In 1942, as the Jennings Radio Manufacturing Company, Jennings was the original innovator of the first high voltage, vacuum variable capacitor. This resulted in a small, lightweight, contamination-resistant capacitor that offered long, maintenance-free service life and the ability to withstand transients that destroy other types of capacitors. Jennings vacuum capacitors have been an industry leader ever since. We’ve extended our technology to include many types of fixed and variable vacuum capacitors, gas capacitors, vacuum and gas relays, contactors, interrupters and coaxial relays. Vacuum assures oxidation-free surfaces and a dielectric that is self-healing when subject to transient over-voltage conditions.

Need something you don’t see in our catalog?

Some manufacturers don’t want to be bothered with non-standard orders. At Jennings, we welcome your unique applications. Our in-house engineers will work with you to custom design a capacitor from an original concept, or to modify one of our standard models. This catalog contains a sampling of our standard models, from which a variety of modifications are possible. Some common requests from our customers include:

• Corona Rings — For applications where adjacent components or areas of different electrical potential can cause corona, or breakdown, we can add corona rings to the edge of the ceramic body to eliminate this occurrence.

• Metric Mounting Threads — In most cases, Jennings capacitors can be supplied with metric mounting threads in place of Unified National (English) threads, or in combination (with both English and metric threads).

• Non-Magnetic Capacitors — Most Jennings capacitors can be supplied as non-magnetic versions, using all non-magnetic materials necessary for critical applications, such as MRI or NMR.

If none of our standard capacitor models meet your needs, our engineers will work with you to design a custom solution that will. Call us today at 408-292-4025 to discuss your application.

Features of Jennings vacuum capacitors

• High Voltage Rating — The dielectric strength of the vacuum permits optimized voltage rating for a given size and capacity, in addition to freedom from contamination, humidity and oxidation.

• High Current Rating — Low losses and rugged copper construction permit the handling of high RF currents with convection cooling only. Some of our designs offer water and air cooling for extraordinary load conditions.

• Wide Tuning Ranges — High ratio of maximum to minimum capacity (up to 175:1) make Jennings vacuum capacitors desirable for wide tuning ranges.

• Low Losses — Losses in a vacuum capacitor are so small that for most applications they can be considered as negligible. Construction materials and the vacuum dielectric permit the handling of large RF currents at high RF frequencies that would destroy capacitors with other dielectrics.

• Self-Healing — Jennings vacuum capacitors can withstand momentary overloads that would permanently damage other dielectric materials.

• High Altitude Operation — Vacuum sealing permits the operation of Jennings vacuum capacitors at high altitudes without the degradation that occurs with other types.

Description and General Specification

Figure 1 illustrates the construction of a typical Jennings variable vacuum capacitor. Two sets of concentric cylinder plates, one adjustable and the other fixed, are enclosed in an evacuated ceramic envelope with OFHC copper seals at both ends. A flexible metal bellows, attached to a sleeve-type bearing, maintains vacuum while allowing capacitance to vary.

The linear sliding motion required to vary capacitance is converted to rotary tuning via an adjustment screw; in many capacitors, direct pull tuning is an alternative.

Internal breakdown voltage is primarily determined by the spacing of the opposing plates and a high vacuum level.

The following are general specifications pertaining to Jennings vacuum capacitors. Current ratings are for normal convection cooling in ambient temperature of 25°C unless otherwise specified.

Maximum Allowable Operating Temperature ........125°C (257°F) for ceramic capacitor

Current/Voltage

Maximum operating current for vacuum capacitors is limited by temperature rise and working voltage. At lower frequencies, a capacitor is a current-limiting device as a result of its capacitive reactance. At some frequencies, the internal generation of heat exceeds the device’s heat-sinking capabilities, and its current-carrying capacity is limited by thermal considerations. A current vs. frequency chart is provided for each capacitor listed.

Peak voltage is limited by mechanical design of the capacitor. It does not vary with frequency.

Temperature

Jennings Technology vacuum capacitors are designed to meet MIL-C-23183 specifications. Our capacitors are rated for a maximum operating temperature of 125°C (257°F) with normal convection cooling at an ambient temperature of 25°C (72°F).

Current

The current rating provided in the tables in this catalog is the maximum current the vacuum capacitor at maximum working voltage can handle continuously under normal convection cooling at an ambient temperature of 25°C.

Pulse Ratings — Continuous RF current ratings may be exceeded for short periods if the working voltage rating is not exceeded. This applies particularly to pulse and peaks-of-modulation applications. Momentary currents may exceed the catalog continuous current rating by a factor of the square root of the duty cycle, provided the working voltage is not exceeded.

Amplitude Modulation Ratings — Capacitors in AM service must be able to withstand peaks-of-modulation voltage and current.

Current ratings are based on temperature, so the heating effects of the modulated currents determine the capacitor requirements.

The average output power of an AM transmitter that is 100% sine wave modulated is 1.5 times the unmodulated carrier power. The average modulated carrier current is 1.225 times the unmodulated carrier current. Therefore, a capacitor current rating of 1.2 times the carrier current will be sufficient, even though the peaks-of-modulation currents are twice the carrier current.

High-current applications?

Jennings pV series capacitors set a new standard for vacuum variable capacitors.

One of the latest innovations to emerge from Jennings Technology, the PV Series of vacuum variable capacitors was designed to withstand rugged, high-current environments to meet the increasing demands of semiconductor-processing applications.

Jennings quality engineers put the PV Series capacitors through rigorous testing. All tested units achieved more than 2.5 million cycles while still meeting their original specifications, and many exceeded 3.8 million cycles. For detailed test results, contact Jennings at 408-292-4025 or visit www.jenningstech.com/technotes/high_ratings.shtml.

Jennings offers PV Series vacuum variable capacitors in 500, 1000 and 2000pF capacitance. Look for them on pages 23, 30 and 35 of this catalog.


Forced Air Cooled and Water Cooled — If higher current ratings are required, capacitors are available with forced-air cooled bellows to operate safely at 200% of the convection-cooled rating. They are identified with a “CAV” model number. Water-cooled capacitors, identified with a model number beginning with “CW,” are also available and are normally limited only by voltage.

On standard convection-cooled capacitors, current rating may be exceeded for short periods of time, providing the rated temperature rise is not exceeded. Under no conditions should the current exceed 150% of convection current rating.

Fixed capacitors can carry more current because they have shorter RF impedance paths. Fixed capacitor current ratings may be increased by forced-air cooling up to voltage and temperature limitations.

Voltage

Two voltage ratings are provided in our product specifications: AC Test Voltage and Working Voltage.

AC Test Voltage is the maximum 60 Hz voltage that can be applied to the capacitor without breakdown occurring, as indicated by either internal or external arc-over. Capacitors are tested at this voltage as a means of determining the general condition of the capacitor. Customers frequently use such a test in incoming inspection to check for damage in transit. External arc-over is usually an indication of external contamination or high humidity, not a deficient capacitor.

RF Working Voltage is the maximum peak RF voltage that can be applied continuously to the capacitor without affecting its ability to withstand instantaneous overloads. It has been established as 60% of the Peak Test Voltage rating. The difference between the 60 Hz Test Voltage and the Working Voltage values is the recommended operating safety factor.

For variable capacitors, the voltage rating is essentially constant from maximum capacity to a point near minimum capacity, where it increases significantly. Within the normal accuracy of instrumentation (±3%), voltage ratings should not be exceeded. Jennings RF testing facilities monitor the above characteristics on a 100% basis, and can also do special application testing when required.

DC —Vacuum capacitors should not be operated at DC voltage above the peak RF working voltage.

DC plus RF —For DC plus RF applications, the sum of the DC plus the peak RF voltage should not exceed the peak RF working voltage.

Capacitors for DC plus RF applications are tested for DC emission on a dielectric strength tester. To meet Jennings Quality Assurance standards, the DC emission current must not exceed ten microamps at the rated working voltage.

Amplitude Modulation —The peak output power of an AM transmitter that is 100% sine wave modulated is 4.0 times the unmodulated carrier power. The peak RF voltage will be twice that of the unmodulated carrier, and the capacitor should have an RF working voltage rating equal to or greater than this voltage.


Capacitance

Fixed capacitors with a nominal capacitance above 50 pF shall be within ±5%. Capacitors with a nominal capacitance of 50 pF or less shall be within ±10%, or .5 pF, whichever is greater. For variable capacitors, the low end will be equal to or less than minimum rating. The capacitance change is substantially uniform with rotation, and there are no capacitance reversals. Capacitance is within ±10% of the nominal value of the curves shown (Capacity vs. Turns), in the linear portion of this curve.

Automatic Shorting Feature

Some variable capacitors have been designed with an internal shorting device that shorts out the capacitor when it has been turned beyond maximum rated capacitance. This feature is useful for tuning antenna couplers without the vacuum capacitor in the circuit and also serves as a reference point for adjusting the capacitor to a previously measured capacitance value.

Adjustable Capacitors

Jennings Technology capacitors with a model number beginning with a “CAC” or “CAD” designation are adjustable capacitors, designed to be operated as a fixed capacitor, but able to be hand adjusted to any value within their range and then locked in position with a locking nut.

Tracking

Pairs of variable capacitors will track within 10% if set together near the low capacity end of the linear portion of the curve. On special order, units may be obtained to closer tracking tolerances.

Torque/Direct Pull

In variable capacitors, the linear sliding motion of the moving electrode assembly is converted to rotary tuning via a threaded shaft. The torque values given in the tables are the maximum torque needed to reach minimum capacitance when rotated with a standard lead screw; the torque required to tune away from minimum may be less than half this value.

For most variable capacitors, direct pull tuning is an available option to rotary tuning. Maximum required direct pull force values are also given in the tables.

Capacitance range end-stops are built into every variable capacitor. It is recommended that the user install their own external stops to prevent damage from gear-reduction drives.

Quality Factor (Q)

Extremely low losses occur in vacuum capacitors because of the vacuum dielectric, compact construction and use of low-loss ceramic envelopes, as well as copper and precious-metal solder construction. Consequently, vacuum capacitors are able to handle large RF currents at high RF frequencies that would destroy other types of capacitors. The Q factor, or ratio of stored energy to dissipated energy, is typically in the order of 1000 to 5000 and higher.

Equivalent Series Resistance (ESR)

Because Q is a function of frequency, capacity and ESR (Equivalent Series Resistance), it is perhaps more meaningful to consider the value of ESR. In modern high power capacitor applications, ESR is significant for determining cooling requirements. The slight loss results from the RF resistance in the copper. Based on actual tests, the ESR value is not affected by change in capacity, other parameters being fixed. The value of ESR varies over a range of 2 to 20 milliohms from 2 to 30 MHz.


Thermal Stability

Jennings vacuum capacitors are designed to meet MIL-C-23183 specifications, which state that the absolute value of the capacitance change with temperature shall not exceed 1.1% over the applicable operating temperature range. In typical tests, values for ceramic capacitors show a stability within 50 ppm/°C.

Salt Spray and Humidity

Jennings capacitors are designed to withstand the harmful effects of salt spray and humidity without degradation in performance.

Inductance

The self-inductance of vacuum variable capacitors is typically in the order of 6 to 20 nanohenries, while that of a fixed capacitor is significantly lower, in the range of 2 to 6 nanohenries.

For most applications, the self-inductance can be ignored. It becomes a factor only when the ratio of capacitive reactance to inductive reactance is small.

Mechanical Life

The mechanical life of variable capacitors is related to length of stroke, speed of operation, bellows material and total number of cycles. Extensive mechanical life tests have been run, operating units for complete cycles from maximum to minimum and back to maximum capacity covering 95% of the full stroke of the movable plates. Capacitors with a large bellows and a short stroke will have the greatest life expectancy under cycling operation. Our most recent variable capacitor models are rated for > 3 million cycles, ideal for the semiconductor processing industry.

Jennings application engineers will be happy to review your specific application to ensure that the optimum capacitor is selected to meet your requirements.

Capacitors in Parallel

When two or more capacitors are connected in parallel, the inductance of the connecting conductors acting with the capacitors form a tuned circuit.

In high current circuits, it is possible to parallel two or more vacuum capacitors to increase capacity. Care must be taken, due to the low loss of the vacuum capacitors and the heavy copper straps paralleling the capacitors, to ensure that the frequency of this series high-Q resonant circuit is above the operating frequency. If the frequency of the series resonant circuit is allowed to become equal to the operating frequency, high currents will be generated, resulting in damage to the capacitor.

All vacuum capacitors have inductance within the connections (Figure 3). The resulting tuned circuit of two 1000pF capacitors in parallel can be kept well above 30 MHz. At low capacities of 50 to 100pF, the resonant frequency can be kept well above 100 MHz.

Figure 4 is a graph of resonant frequency vs. capacity of two 1000pF capacitors with low inductance connections. The resonant frequency of the resulting parellel tuned circuit varies from 20 MHz to 135 MHz from a maximum to minimum capacity.

Testing Standards

Factory — All capacitors are tested for dielectric strength on a 100% basis prior to shipment. Upon customer request, certified test reports will be made available.

Dielectric strength is tested using a low current, high potential source at 60 Hz voltage.

Capacitors for applications involving applied DC voltage should be tested on a DC dielectric strength meter for voltage and emission current. Jennings will test capacitors to this measure if specified by the customer.

User — Most users will find the 60 Hz dielectric strength test adequate and relatively inexpensive. Jennings does not recommend DC testing being performed by the user because of safety considerations. If DC testing is performed, care should be taken not to exceed 60% of the peak test voltage rating of the capacitor.

Testing Procedure

Apply 60 Hz current-limited voltage across the capacitor. One side may be grounded if desired.

Increase voltage gradually. The rate of increase should be from zero to maximum voltage in one minute. Normal test procedure requires that the capacitor be able to withstand the full rated voltage without barnacles (arcing) occurring after the first minute at the test voltage. A barnacle is a self-healing, non-sustained, momentary breakdown. Weak barnacles that instantly heal are disregarded during the first minute. Under no condition should the test voltage be exceeded.

Arc Detectors — In extremely critical circuit applications, some form of arc detection is necessary. An oscilloscope may be connected across the capacitor to show weak electron discharges, waveform distortion, evidence of strong DC emission currents or corona.

Another form of arc detection may be improvised by using a small neon lamp with one terminal connected to the hot side of the capacitor under test and the other terminal of the lamp floating. The lamp will flash when the capacitor arcs. A contact microphone and audio amplifier connected to the base of the standoff insulator supporting the capacitor under test also makes a very sensitive arc detector.

Installation

Testing — Jennings vacuum capacitors are well packaged and shipped in a manner to ensure safe delivery. However, during shipping they may be subjected to extreme shock, which could damage the capacitor elements without damaging the shipping container. Therefore, capacitors should be tested upon receipt and before installation. (See Capacitor Testing Procedure above.)

HiPot Testing of Vacuum Capacitors — The most important test for vacuum capacitors is the high voltage AC HiPot test. It is the indicator of the standoff capability of a capacitor. If the vacuum level of a capacitor decays or there is misalignment of the plates, the standoff capability of the capacitor will be reduced. This test is performed by applying a 50 or 60 Hz AC voltage up to the specified Test Voltage (ETest) of the capacitor. The lower the frequency of a HiPot test, the more stringent it is. Therefore, 50 or 60 Hz is used, even for capacitors to be used in RF applications. Capacitors to be used in DC applications should not be subjected to a DC voltage above the specified Operating Voltage, which is ≤ 60% of the Test Voltage.

Personnel: Trained and qualified to work safely with high voltages.

Equipment: HiPot tester that is certified to meet appropriate government safety standards or an approved variable AC power supply capable of supplying the voltage required with a current-limiting resistor (R ≥ ETest/Imax) in series between the power supply and the capacitor.


Procedure: 1. Apply ~ 1 kV @ 50 or 60 Hz to the electrodes. Increase the voltage at

a rate of 20 kV per minute up to ETest unless there is internal arcing (barnacling) or current flow greater than the charging current of the capacitor that persists for > 2 seconds. In that case, reduce the voltage until barnacling terminates, observe voltage and repeat the process. Continue this process as long as the voltage where arcing is encountered continues to increase up to ETest.

2. If there is any external arcing at any voltage, clean the external surfaces. If conditions are extremely humid, delay testing until it can be done in a lower humidity.

3. Upon experiencing any barnacling or current flow greater than the charging current of the capacitor that persists for > 2 seconds, reduce voltage until barnacling terminates, observe voltage and repeat the process. Continue this process as long as the voltage where arcing is encountered continues to increase up to ETest and is held there for one minute without barnacling or exhibiting current flow greater than the charging current of the capacitor.

4. If there is no persistent barnacling or current flow greater than the charging current of the capacitor (up to ETest), the capacitor has passed the HiPot test. If barnacling is encountered, it is not necessarily a bad capacitor, but it may require reconditioning.

Warning — During installation, avoid twisting or bending strains that could cause failure of the ceramic-to-metal seal.

Mounting Position — Units may be mounted in any position. When large capacitors are mounted horizontally, both ends should be supported by standoff insulators to eliminate excessive stresses and possible damage. (Vertical mounting preferred.)

Cooling — Current ratings are determined on the basis of convection cooling only. It is good design practice to provide an added safety factor by having the variable end mounted on the chassis for heat sinking and by using flexible copper straps for the fixed electrode end. When a large capacitor is being operated near its maximum current rating at high frequencies, there must be adequate space around the unit for convection cooling.

Water Cooling — Consult factory for specific recommendations.


Procedure: 1. Apply ~ 1 kV @ 50 or 60 Hz to the electrodes. Gradually

increase the voltage up to ETest unless there is internal arcing (barnacling) or current flow greater than the charging current of the capacitor that persists for > 2 seconds. In that case, reduce the voltage until barnacling terminates, observe voltage and repeat the process. Continue this process as long as the voltage where arcing is encountered continues to increase up to ETest.

2. If there is any external arcing at any voltage, clean the external surfaces. If conditions are extremely humid, delay testing until it can be done in a lower humidity.

3. Upon experiencing any barnacling or current flow greater than the charging current of the capacitor that persists for > 2 seconds, reduce voltage until barnacling terminates, observe voltage and repeat the process. Continue this process as long as the voltage where arcing is encountered continues to increase up to ETest. The capacitor should be held at ETest for one minute without current flow or barnacling. Leave ETest applied for 15 to 20 minutes to complete this session of conditioning.

4. If barnacling is encountered at the same voltage or lower for three successive attempts, discontinue reconditioning. If the capacitor is in warranty, call Jennings Technology’s QA Department at (408) 282-0335 and request an RMA number. Then return it to the factory for evaluation. If it is out of warranty, dispose of it in a safe manner.

5. If conditioning as described in paragraphs 3 and 4 was required, but it passes the one-minute test without current flow or barnacling, allow it to rest for at least 24 hours and repeat the conditioning process for up to three sessions. If it passes the one-minute test described in paragraph 3 after a 24-hour hold, it is adequately conditioned and may be placed into service. If after three sessions, the capacitor continues to barnacle, the capacitor is probably bad.

Vacuum Capacitor Reconditioning

A vacuum capacitor that has exhibited barnacling during incoming inspection, when it has been in storage, or has been used for light duty (low voltage) for a prolonged period may exhibit internal arcing (barnacling) when high voltage is first applied. If this occurs ≤ ETest, it may be an indication that the capacitor needs reconditioning or that it no longer has adequate voltage standoff capability. In this situation, we recommend the following course of action.

Personnel: Trained and qualified to work safely with high voltages.

Equipment: HiPot tester that is certified to meet appropriate government safety standards or an approved AC variable power supply capable of supplying the voltage required with a current-limiting resistor (R ≥ ETest/Imax) in series between the power supply and the capacitor.


Thermal Expansion — To allow for thermal expansion, at least one end of the vacuum capacitor should have a flexible connection. In variable capacitors, the flexible connection is normally made to the fixed electrode end. Avoid heavy rigid straps or connections that produce a mechanical strain. The connections should be of substantial area to keep losses low and provide cooling by conduction from both ends. Only a small degree of flexibility is required.

Electrical Connections — Both ends of the capacitor may be “hot,” or one end may be grounded. Because of the high voltages present, there must be sufficient clearance between the vacuum capacitor and other components to prevent high voltage breakdown. Although the capacitors are designed to ensure optimum electrical field distribution, mounting should be such that adjacent components do not upset this normal electrical field and thus result in excessive heating.

Magnetic Influences — Strong magnetic influences can induce heating and affect performance of capacitors. Electromagnets have greater effect than permanent magnets.

Transients and Parasitics — Where the possibility exists of external arcs from transients or parasitic voltages, the capacitor should be protected by adequate corona, or arc shields. Ball gaps are recommended when protection from simple voltage arc cover is required.

Lead Lengths — At high frequencies, avoid long lead length, because the reactance of the strap will subtract from the reactance of the capacitor and effectively increase the total capacitance. In some cases, the total reactance may be reduced to the point where the minimum capacity of the capacitor will appear too high.

Side Loading — Side loading (radical force applied to lead screw) will greatly accelerate wear and significantly reduce life. A flexible coupler connection to the lead screw is highly recommended. Increased frequency of 100% minimum to maximum cycling will also be helpful. (See Maintenance.)

Other Precautions — Capacitors should not be used as standoff insulators to support heavy assemblies.

Only the part of the capacitor specified as the mounting area should be used for that purpose, and any clamps or straps must be attached carefully to avoid stress on the unit, possibly causing seal failure.

Solder connections should not be made directly to the body of the capacitor, nor should there be any contact with the ceramic insulator during operation.

Maintenance

Capacitors operated at normal temperature in a clean environment require no maintenance except to keep them free of dirt accumulation and moisture that may cause a drop in external insulation resistance. A special glaze is applied to all Jennings ceramic capacitors to avoid absorption of moisture and foreign matter.

For variable capacitor applications involving frequent adjustment over a limited range, such as semiconductor impedance matching, it is advisable to cycle completely between minimum and maximum at least 2 cycles every 10,000 cycles to redistribute lubricant.

If variable capacitors are being operated at high temperatures, it is advisable to periodically lubricate the shaft and bearing with a good grade of high temperature light oil and the lead screw with a high temperature, extreme pressure grease.
