Greenville, S.C. -- KEMET Corp. has launched its High Voltage-High Temperature (HV-HT) Series of 200 degrees C, surface-mount ceramic capacitors in a C0G dielectric. Delivering high performance at extreme temperatures, the HV-HT capacitors are said to offer greater volumetric efficiency over competitive high temperature precious metal electrode (PME) and base metal electrode (BME) ceramic capacitor devices.
The HV-HT Series is specifically designed to withstand harsh industrial environments in down-hole oil exploration, aerospace engine compartments, geophysical probes, under-the-hood automotive and defense markets. Typical applications include critical timing, tuning, circuits requiring low loss, circuits with pulse, high current, switch mode power supplies, high voltage coupling, DC blocking and voltage multiplier circuits.
"KEMET's new HV-HT Series capacitors retain high insulation resistance with high breakdown voltages and low dissipation factors at elevated temperatures up to 200 degrees C," said Dr. Abhijit Gurav, KEMET vice president of ceramic technology, in a statement. "They also exhibit low ESR at high frequencies and offer superior performance over existing X7R, BX and BR dielectric technologies. In addition, these capacitors are Lead-Free, RoHS and REACH Compliant without the need of any exemptions."
