KEMET has launched the KPS-MCC COG High Temperature 200 Degree Celsius bulk capacitance solution for harsh environment applications.
Developed by combining KEMET’s robust and proprietary COG/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 COG BME dielectric system is designed to provide high reliability at operating temperatures up to 200 degrees Celsius, while maintaining high insulation resistance, very low ESR and very high ripple current capability at high frequencies.
In addition, this series provides superior stability with no capacitance change versus DC voltage and ±30 ppm/°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 excellent mechanical robustness. Superior electrical performance, high reliability, and mechanical robustness of KEMET’s BME COG dielectric results in a preferred solution over CLASS II (X7R/X5R) capacitors above 175 degrees Celsius.
Available in three case sizes, the KPS-MCC series offers voltages up to 2,000 V and capacitance up to 2 microfarads 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 COG offering extends KEMET’s portfolio up to 2 microfarads in a Class I solution,”, says KEMET VP Dr. John Bultitude, ” with KEMET’s temperature-cycling resistant frame technology and high ripple current capability, these bulk capacitance solutions provide unparalleled performance for the harshest environments on, under and above the Earth.”
