KEMET Announces First-to-Market High Temperature Ceramic C0G Dielectric Capacitors in 0402 Case Size

GREENVILLE, S.C., June 29, 2011 /PRNewswire/ -- KEMET Corporation (NYSE: KEM), a leading manufacturer of tantalum, ceramic, aluminum, film, paper and electrolytic capacitors, today announced the release of the industry's first Multilayer Ceramic Capacitor (MLCC) in an EIA 0402 case size capable of reliable performance in environments up to 200 degrees C.

KEMET's High Temperature 200 degrees 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 degrees C. This platform promotes downsizing opportunities of existing high temperature C0G technology and offers replacement opportunities for existing X7R/BX/BR technologies.

"KEMET's industry-leading C0G technology continues to outperform X7R in the most extreme environments. With virtually no capacitance change at 200 degrees C and rated voltage, C0G actually has a higher effective capacitance than most X7R options," said Bill Sloka, KEMET Specialty Product Manager. "Our 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.
