Ultra-Stable X8R and Stable X8L “Aximax” Ceramic Capacitors

KEMET Electronics announces two 150°C axial ceramic capacitors

Image of Kemet's Ultra-Stable X8R and Stable X8L “Aximax” Ceramic CapacitorsKEMET's Aximax conformally coated axial through-hole ceramic capacitors in X8L dielectric feature a 150°C maximum operating temperature and are 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. Beyond 125°C X8L displays a wider variation in capacitance. 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.

KEMET's Aximax conformally coated axial through-hole ceramic capacitors in Ultra-Stable X8R dielectric feature a 150°C maximum operating temperature, offering the latest in high temperature dielectric technology and reliability for extreme temperature applications. It offers the same temperature capability as conventional X8R, but without the capacitance loss due to applied DC voltage. Ultra-Stable X8R exhibits no change in capacitance with respect to voltage and boasts a minimal change in capacitance with reference to ambient temperature. It is a suitable replacement for higher-capacitance and larger-footprint devices that fail to offer capacitance stability. Driven by the demand for a more robust and reliable component, the Ultra-Stable X8R dielectric Aximax through-hole capacitors were developed for critical applications where reliability and capacitance stability at higher operating temperatures are a concern.

Available in standard or automotive grade base-metal electrode (BME) dielectric systems, these capacitors offer a variety of features and benefits.
