KEMET has released new High Temperature Surface Mount C0G multilayer ceramic capacitors (MLCCs) that feature 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.
The new devices have low ESR and ESL and high ripple current capability. The 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 the non-polar devices range from 0.5 pF up to 0.22 μF in capacitance tolerance offerings of ±0.25pF, ±0.5pF, ±1 percent, ±2 percent, ±5 percent, ±10 percent, or ±20 percent. The Temperature Coefficient of Capacitance (TCC) is ±30ppm/ degrees C from -55 to +200 degrees C. Devices are available in DC voltage ratings of 10 V, 16 V, 25 V, 50 V and 100 V, with a maximum dissipation factor of 0.10 percent.
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.
