KEMET has announced the addition of the EIA 2824, 3040, 3640, and 4540 case sizes to the HV-HT surface mount multilayer ceramic capacitor product line. These added case sizes allow for up to 150nF of temperature-stable capacitance in 200°C environments.

HV-HT capacitors are specifically designed to withstand the demands of harsh industrial environments such as oil exploration and automotive/avionics engine compartment circuitry. In addition, with the growing trend of increased voltage, frequency, and temperature in Wide Band Gap semiconductors (SiC, GaN) technology, KEMET’s HV-HT capacitors are ideal for realizing design goals such as maximum power density and efficiency.

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 in extreme environments such as down-hole exploration, aerospace engine compartments, and geophysical probes.

HV-HT capacitors were developed under KEMET’s patented 200°C high reliability base metal electrode (BME) dielectric platform which is 100% Pb-free, RoHS and REACH compliant without exemptions. In addition to a low profile and aspect ratio, these devices exhibit low inductance and ESR with respect to application frequency, allowing for very high ripple current capability.
