High Temperature +200°C, High Voltage, C0G MLCCs - HV-HT Series

KEMET Electronics, a YAGEO Company, offers high-voltage, high-temperature +200°C capacitors with EIA case sizes of 2824, 3040, 3640, and 4540, providing a maximum capacitance of 150 nF with voltages up to 2000 V. In addition, with the growing trend of increased voltage, frequency, and temperature in wide band gap semiconductors (SiC, GaN) technology, KEMET’s patented Class-1 base metal electrode (BME) capacitors are ideal for realizing design goals such as maximum power density and efficiency.

The HV-HT series of surface-mount C0G MLCCs are constructed of a robust and proprietary base metal electrode (BME) dielectric system that offers excellent performance at extreme temperatures. These devices feature a +200°C maximum operating temperature and are specifically designed to withstand the demands of harsh industrial environments such as oil exploration and automotive or avionics engine compartment circuitry.

These MLCCs are temperature compensating and are suited for resonant circuit applications or those where Q and stability of capacitance characteristics are required. They exhibit no change in capacitance with respect to time and voltage and boast a negligible change in capacitance with reference to ambient temperature. Capacitance change is limited to ±30 ppm/°C from -55°C to +200°C. In addition, these capacitors exhibit high insulation resistance with a low dissipation factor at elevated temperatures up to +200°C. They also exhibit low ESR at high frequencies and offer superior volumetric efficiency over competitive high-temperature precious metal electrode (PME) and BME dielectric system devices. These devices are lead (Pb)-free, as well as RoHS and REACH compliant, without requiring any exemptions.
