Global supplier of electronic components, KEMET, has announced the launch of the KPS-MCC C0G High Temperature 200°C bulk capacitance solution for harsh environment applications. Developed by combining KEMET’s robust and proprietary C0G/NPO base metal electrode (BME) dielectric system with durable lead frame technology, these capacitors are suitable for demanding high temperature, high voltage and high vibration applications such as down-hole oil exploration, automotive and hybrid electric vehicles (HEV), defense and aerospace.

The KEMET C0G BME dielectric system is designed to provide high reliability at operating temperatures up to 200°C, while maintaining high insulation resistance, low ESR and high ripple current capability at high frequencies. In addition, this series provides stability with no capacitance change versus DC voltage and ±30ppm/°C capacitance change over temperature.

A high melting point (HMP) solder for lead attachment enables multiple chips to be stacked in parallel to provide bulk capacitance with mechanical robustness. Electrical performance, high reliability, and mechanical robustness of KEMET’s BME C0G dielectric results in a preferred solution over Class II (X7R/X5R) capacitors above 175°C.

Available in three case sizes, the KPS-MCC series offers voltages up to 2,000V and capacitance up to 2µF in a footprint of less than 0.55 square inches. Each case size can be ordered in a straight pin, formed 'L', or formed 'J' configuration and with a silver (Ag) or solder coated (SnPb) termination finish.

“This latest addition to KEMET’s world-class BME C0G offering extends KEMET’s portfolio up to 2µF in a Class I solution,” said Dr. John Bultitude, KEMET Vice President and Technical Fellow. “With KEMET’s temperature-cycling resistant lead frame technology and high ripple current capability, these bulk capacitance solutions provide unparalleled performance for the harshest environments on, under and above the Earth.”
