KEMET Launches a New High Temperature C0G Dielectric Platform

GREENVILLE, S.C., Feb. 2 /PRNewswire-FirstCall/ -- KEMET Corporation (OTC Bulletin Board: KEME.OB), a leading manufacturer of tantalum, multilayer ceramic, solid aluminum, plastic film, paper and electrolytic capacitors, today announced the release of a new high temperature C0G dielectric platform.

KEMET's new High Temperature Surface Mount C0G MLCCs 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 new platform promotes downsizing opportunities of existing High Temperature C0G technology, and offers replacement opportunities for existing X7R/BX/BR technologies.  

"Our High Temperature C0G MLCCs offer no capacitance change with respect to applied DC voltage, temperature, and time as demonstrated by Class II dielectrics systems, such as X7R Dielectric," stated Jeff Franklin, Specialty Product Manager for KEMET.  "Our customers in the Down Hole, Industrial, Military and Aerospace markets require the higher capacitance, temperature stability and reliability this new platform offers," continued Franklin.

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

Technical Data for the High Temperature COG Dielectric Platform

Standard capacitance ratings for these devices range from 0.5 pF up to 0.22 uF in capacitance tolerance offerings of +/-0.25pF, +/-0.5pF, +/-1%, +/-2%, +/-5%, +/-10%, or +/-20%. The Temperature Coefficient of Capacitance (TCC) is +/-30ppm/degrees C from -55 degrees C to +200 degrees. Devices are available in DC voltage ratings of 10V, 16V, 25V, 50V and 100V, with a maximum dissipation factor of 0.10%.

Seven standard EIA case size options are available which include –0603, 0805, 1206, 1210, and 1812- with either nickel barrier/tin or Sn/Pb terminations.  

Other features include:

• No piezoelectric noise.
• Extremely low ESR and ESL.
• High thermal stability.
• High ripple current capability.
• Preferred capacitance solution at line frequencies and into the MHz range.
• No capacitance change with respect to applied rated DC voltage.
• Minimal capacitance change with respect to temperature from -55 degrees C to +200 degrees C.
• No capacitance decay with time.
• Non-polar device.

Samples and production quantities of KEMET 200 degrees C High Temperature C0G MLCCs are available now.  For more information on this and other KEMET High Temperature products please visit: http://www.kemet.com/kemet/web/homepage/kechome.nsf/weben/Hi%20Temp.
