KEMET has rolled out its high voltage-high temperature (HV-HT) series of 200℃-capable surface mount ceramic capacitors. The devices offer patented C0G dielectric technology and better volumetric efficiency compared with high-temperature precious metal electrode (PME) and base metal electrode (BME) ceramic capacitor devices, according to the company.

The HV-HT series capacitor is specifically designed to withstand harsh industrial environments in down-hole oil exploration, aerospace engine compartments, geophysical probes, under-the-hood automotive, and defence 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℃," said Dr. Abhijit Gurav, KEMET Vice President of Ceramic Technology. "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."
