Evaluation of 10V Chip Polymer Tantalum Capacitors for Space Applications
benefit of chip polymer tantalum capacitors (CPTCs) is a relatively safe failure mode. Contrary to MnO2 capacitors that often fail with ignition causing damage to the whole system, failures in polymer capacitors are much less dramatic. In order to prevent surge current failures that are specific to MnO2 capacitors, operation voltages should be de -rated. Due to different …
