High-Temperature 0402 Capacitors

KEMET's high temperature +200°C series features a robust and proprietary base metal dielectric system that offers industry-leading performance relative to capacitance and case size combined with capacitance stability at extreme temperatures up to +200°C. This platform promotes downsizing opportunities of existing high temperature C0G technology and offers replacement opportunities for existing X7R/BX/BR technologies.

KEMET 's C0G technology continues to outperform X7R in the most extreme environments. With virtually no capacitance change at +200°C and rated voltage, C0G actually has a higher effective capacitance than most X7R options. Customers in the down-hole, industrial, avionics, and automotive markets require the higher capacitance, temperature stability, reliability, and reduced size this platform offers.

Typical applications include critical timing, tuning, circuits requiring low loss, circuits with pulse, high current, decoupling, bypass, filtering, transient voltage suppression, blocking, and energy storage for use in extreme environments. High temperature environments are commonly present in down-hole exploration equipment, aerospace engine compartments and geophysical probes.
