Tantalum & Polymer Tantalum Capacitors

A Tantalum Polymer capacitor basically consists as well as a conventional Tantalum capacitor of a sintered Tantalum block. (Anode)

The dielectric is Tantalum pentoxide (Ta2O5) which is used as an isolating layer.

The next layer is, in opposite to the conventional Tantalum technology, a high conductive Polymer. (Cathode)This organic material enables an enormous improvement of the capacitor’s performance.

Tantalum Polymer Capacitors are opening up opportunitiesfor designers to shrink the size of their products andadd new functionality in a wide range of applications.This technology enables to reduce the overall number ofparts required, due to its lower ESR and increasing layoutflexibility.

The Electronic Industry had and still has to handle the sophisticated requirements of the customers. The applications are getting more and more powerful, smaller and of higher quality.That’s the reason why also Tantalum and Polymer Tantalum Capacitors have always to improve their technical parameters to satisfy the constantly changing requirements of the applications.According to this changes there are three main developments within this capacitor-family noticeable: Small case sizes and low profile series

for space-saving layout Lower ESR-values (series resistance)

for higher pulse frequencies Higher capacities for known case sizes

for more powerful applications

Such products will only be achievable by the use of improved raw materials and clever designs but also by total new material technologies. For example the volumetric efficiency of the tantalum powder has steadily increased over time, which allows the production of larger and larger capacitances with the same physical volume.

New methods of development establish new possibilities such as the multi-anode configuration of capacitors. Furthermore, the usage of new materials provided capacitors with new features. One example is the Polymer Tantalum Capacitor, where a high conductive cathode is used to achieve extremely low ESR values.

Because of the close partnership with the worldwide leading manufacturers we are in a position to offer our customers the ideal range of capacitor technology for their applications from a tech-nical as well as cost-effective view - every time.

Voltage Derating

Fig.2. Temperature Correction Factor *Fig.1. Tantalum & OxiCap® reliability curve *

Parameters Sensitive to DeratingThere are three main parameters sensitive to the level of derating (ratio between applied voltage and rated voltage of the capacitor): Steady State Failure Rate, Dynamic Failure Rate (resistance to surge current / low external resistance) and DCL at application voltage.

Reliability of failure rateSteady State Failure RateBoth Tantalum and Niobium Oxide dielectric have essentially no wear out mechanism and in certain circumstances are capable of limited self healing. However, random failures can occur in operation. The failure rate of Tantalum capacitors will decrease with time and not increase as with other electrolytic capacitors and other electronic components. – see Fig. 1.

The useful life reliability of the tantalum capacitors in steady state is affected by three factors. The equation from which the failure rate can be calculated is:

where:FV - correction factor due to operating voltage/ voltage derating – see Fig. 2.FT - correction factor due to operating temperature– see Fig. 3.FR - correction factor due to circuit series resistanceFB - basic failure rate level

Base failure rateStandard Tantalum conforms to Level M reliability (i.e. 1%/1000 hrs) or better at rated voltage, 85°C and 0.1Ω/volt circuit impedance.

FB= 1.0% / 1000 hours for commercial tantalum series and tantalum polymer capacitors

0.5% / 1000 hours for professional tantalum series TRJ, TRM, THJ

0.2% - 0.5% / 1000 hours for niobium series

Dynamic Failure Rate (Surge Current)Protection against uneven current surges in low impedance circuits is the most important factor to consider an appropriate derating factor of tantalum capacitor. The worst case of current surge in the application should not exceed the design and screened current of the capacitor specified by the manufacturer.

Current through capacitorThe maximum surge current (transient) through the capacitor in a circuit is defined by two factors:

a) Power supply output

The current developed during power up (charging, transient) through the capacitor depends on the power supply:

where:CX = capacitance of the capacitordV/dt = voltage gradient(how fast the power supply can ramp the voltage)

F = FV ∙ FT ∙ FR ∙ FB

I=CX ∙ [A]dVdt

b) Ohm´s law

where:V = application voltageR = total resistance of the circuit

The actual current through the capacitor is defined by the lower value calculated from equations [a] and [b].

Solid Tantalum capacitors have a limited ability to withstand voltage and current surges. Such current surges can cause a capacitor to fail. The expected failure rate cannot be calculated by a simple formula as in the case of steady-state reliability.The table below summarizes a the result of trials made by one of our manufacturers.

As can clearly be seen from the results of this experiment, the more derating applied by the user, the less likely the probability of a surge failure occurring.

DCL - leakage current in the applicationThe leakage current drops rapidly below the value corresponding to the rated voltage VR when reduced voltages are applied.

DCL value can typically drop to one range lower value if 50% derating is used – see Fig. 4.

Example: typical DCL of 10V capacitor used at different operating voltage.

Voltage derating is necessary for all tantalum, niobium and polymer capacitors to prevent failure due to excess current availability.

Recommended Voltage Derating Guidelines

However for tantalum polymer capacitors and capacitors made from niobium oxide, the failure-rate has less dependence on applied voltage and have different derating requirements. Hence a minimum derating of 20% is sufficient in all applications.

Comparison of Tantalum & Multilayer Ceramic Capacitors

IntroductionIn many business fields like measurement, automotive and industry electronics, there are more often intentions to replace tantalum capacitors through MLCC’s. However the replacement is not always an ideal solution, because the capacitors have built-in specific kinds of features suitable for desired equipments.

There are significant differences in constructions between multilayer ceramic (MLC) and tantalum capacitors. The ceramic MLC chip is a ceramic block with end metallizations applied to the opposing end termination faces (T1 & T2).This creates wrap-around metal pads on the adjacent faces, and these pads are soldered directly to the printed circuit board (PCB) along the bottom of the chip.

The active element of the tantalum capacitor is a metal-dominated structure that is encased in plastic, with leadframes extending out from the plastic to allow a leadframe wrap-under (T1 & T2), which creates metal pads along the bottom of the package to facilitate the soldering to the PCB.

Parasitic ESR and ESLBoth of these capacitors have parasitic ESL and ESR, simply because of the physics involved in manufacturing the devices.Both technologies have a finite length and width of conductor in which the conduction currents flow through, therefore they both have inductance (ESL).

The ESR of MLCC’s is typically lower than that of similar value tantalum. The ratio of this parasitic is typically 1:100. Using conductive polymers in place of the traditional MnO2 cathode reduces this ratio down to 1:10 and, in some cases approaching unity – see Fig. 1.

Temperature Coefficient of capacitanceThe allowable change in capacitance for two of the ceramic dielectrics and for tantalum within their temperature ranges are all within a +-15% window – see Fig. 2.

For filtering applications, they are very similar, as deviations within 20% will have little impact on circuit. For power supplies that are always in the temperature range above 20°C, the higher capacitance from the tantalum could result in lowered impedance and improved performance.

Viewing these same considerations for decoupling of hot microprocessors or decoupling applications, the higher capacitance at elevated temperatures makes the tantalum response more desirable.

DC bias DependencyThe specified capacitance of MLCC’s are related to a specific metering voltage, usually 1V with a frequency of 1 kHz.If there will be a DC voltage applied, the capacitance of the ceramic capacitor will decrease.This effect is called DC bias.

Tantalum capacitors do not change capacitance with applied DC bias.

Since almost all capacitors are operated with a DC voltage invol-ved, this is a very important feature to keep in mind when desi-gning a circuit – see Fig. 4:

It should be noted that the temperature and DC bias effects are cumulative and not exclusively independent.

Piezoelectric noiseDue to the fact that the ceramic material is crystal based it has a potential for piezoelectric noise.In the case of the capacitor mechanically fixed on the board, any mechanical stress created in the part by the board can generate unwanted electrical noise.This is especially important for high-gain amplifiers.

Tantalum capacitors have no piezoelectric effect - see Fig. 5

Flex cracksThe most reported cause for failure of ceramic chips today is flex cracking.

The larger the capacitor chip, the greater possibility for cracking. The larger capacitor chips afford the largest capacitance. Replacing tantalum capacitors usually requires the largest ceramic capacitance available.This creates a self-feeding cycle of failure.

Tantalum capacitors are not affected by mechanical stress.

SummaryThere is no simple answer to the question of whether you can replace a tantalum with a ceramic or the other way around.The parameters that the capacitor will see during its lifetime need to be examined carefully.The benefits of the technologies are listed in the table below.

New 125V Tantalum Polymer SMD Capacitors Surpass Previous 100V Milestone

The new surface-mount chip capacitors have surpassed previous milestones with the introduction of the new TCJ 100V and 125V to provide excellent capacitance and ultra-low ESR in a compact case size also in the reduced ignition failure mode solution. In addition, due to the nature of polymer capacitors surge robustness, lower derating of 20% can be used. Nevertheless, due to maximum achievable breakdown voltage, working voltage of tantalum-polymer capacitors was limited up until now.

The continuous AVX development proved conductive polymer abi-lity to increase the rated voltage up to 125V, extending the applica-tion voltage up to 100V. This significantly widens the working range of tantalum capacitors for a wide array of high-voltage applications, including telecommunications equipment, base stations, switching hubs, router and line filters, DC/DC converters in LED TVs, Note-book power supplies, and a host industrial applications.

The new, high-voltage TCJ Series tantalum polymer capacitors allow design engineers to reduce the number of components on the board, providing much greater layout flexibility than comparable aluminum electrolytic capacitors and enabling the devices they’re designed into, such as LCD monitors and LED TVs, to become even sleeker and more compact.
