Tantalum capacitor failure modes have been discussed both for the standard manganese dioxide cathode and the new conductive polymer (CP) type. For standard tantalum in the normal operation mode, an electrical breakdown can be stimulated by an increase of the electrical conductance in channel by an ...
In most cases, a decreasing time to failure has been noticed. The specifications generally allow a capacitor variation of − 10% between the measured values at 20 and − 55 °C, and a variation of + 12% between 20 and + 85 °C, respectively. The product CU (capacity × voltage) ...
As has been published elsewhere, polymer tantalum capacitors should share common failure modes with traditional MnO2 products but suppliers insist that they cannot obtain failures using standard Weibull testing. Should polymer capacit...
