Kemet's X8L FT-CAP is well-suited for high temperature bypass and decoupling applications. It utilizes flexible termination technology 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.
The X8L dielectric features a +150°C maximum operating temperature and is considered "general purpose high temperature". These components are fixed, ceramic dielectric capacitors suited for high temperature bypass and decoupling applications or frequency discriminating circuits where Q and stability of capacitance characteristics are not critical. X8L exhibits a predictable change in capacitance with respect to time and voltage and boasts a minimal change in capacitance with reference to ambient temperature up to +125°C. Capacitance change is limited to ±15% from -55°C to +125°C and +15, -40% from +125°C to +150°C.
Driven by the demand for a more robust and reliable component, X8L dielectric capacitors were developed for critical applications where reliability at higher operating temperatures are a concern. These capacitors are manufactured in state of the art ISO/TS 16949:2002 certified facilities and are widely used in automotive circuits as well as general high temperature applications.
