Dielectric C0G +200ºC MLCC | Kemet Electronics

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 +200ºC. This new platform promotes downsizing opportunities of existing High Temperature C0G technology, and offers replacement opportunities for existing X7R/BX/BR technologies. 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.

Standard capacitance ratings for these devices range from 0.5 pF up to 0.22 µF in capacitance tolerance offerings of ±0.25pF, ±0.5pF, ±1%, ±2%, ±5%, ±10%, or ±20%. The Temperature Coefficient of Capacitance (TCC) is ±30ppm/°C from -55°C to +200°C. 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 –0402 (new), 0603, 0805, 1206, 1210, and 1812- with either nickel barrier/tin or Sn/Pb terminations.
