KEMET Commercial & Automotive Flex Mitigation Solutions

KEMET Commercial and Automotive Flex Mitigation Solutions offer a variety of flex mitigation solutions designed to reduce the risk of flex cracks. Flexible termination (FT-CAP) multilayer ceramic capacitors incorporate a unique, flexible termination system that is integrated with the KEMET standard termination materials. A conductive silver epoxy is utilized between the base metal and nickel barrier layers of KEMET’s standard termination system in order to establish pliability while maintaining terminal strength, solderability, and electrical performance.

Floating electrode multilayer ceramic capacitors (FE-CAP and FF-CAP) utilize a cascading internal electrode design configured to form multiple capacitors in series within a single monolithic structure. This unique configuration results in a fail-open condition if mechanically damaged (cracked). If damaged, the device may experience a drop in capacitance, but a short is unlikely.

Open-mode capacitors (FO-CAP) are designed using an electrode pattern that is moved away from the termination area of the MLCC. If a flex crack were to form in the MLCC, the crack would propagate through the ceramic but avoid the active area of the electrodes, leading to a fail-open condition.

KEMET Power Solutions (KPS) stacked capacitors utilize a proprietary lead-frame technology to vertically stack one or two multilayer ceramic chip capacitors into a single compact surface mount package.
