AVX’s FLEXISAFE capacitors were designed to prevent a failure from occurring. They use a cascade design where two capacitors are designed in series within a single MLCC package. Additionally, a conductive epoxy layer is added to the termination between the base metalization and nickel barrier. It should be stressed that the conductive epoxy does not increase the ESR of the capacitor. Additionally, it does not exhibit any low voltage or high humidity failure modes.
