KEMET Expands Flexible Termination System With X8L Dielectric

GREENVILLE, S.C. July 25, 2011

KEMET Flexible Termination Capacitors (FT-CAP) in X8L dielectric reduce ceramic chip failures in high temperature environments. Driven by demand for a more robust component, these devices perform reliably in operating temperatures up to 150 degrees C.

Tim Hollander

Flexible Termination technology was developed to address flex cracks, the industry’s primary failure mode for surface mount multilayer ceramic capacitors (MLCCs). This technology directs circuit board stress away from the ceramic body and into the termination area, therefore reducing the risk of mechanical damage to the component that can result in low IR or short circuit failures.

More Information on the Flexible Termination System

X8L FT-CAP is well-suited for high temperature bypass and decoupling applications. It utilizes a conductive silver epoxy 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. This technology was developed to address flex cracks which are typically the result of excessive shear stresses produced during board flexure or thermal cycling. Flexible Termination technology directs board flex stress away from the ceramic body and into the termination area, therefore mitigating flex cracks which can result in low IR or short circuit failures.
