Additional case sizes boost capacitors to 2,000V
Additional sizes have been added to the HV-HT series of surface mount, multi-layer ceramic capacitors by Kemet.
The company has added EIA 2824, 3040, 3640, and 4540 case sizes, allowing for up to 150nF of temperature-stable capacitance in 200 degree C environments.
The capacitors are specifically designed to withstand the demands of harsh industrial environments such as oil exploration and automotive/avionics engine compartment circuitry.
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.
The capacitors were developed under the company’s 200 degree C, high reliability base metal electrode (BME) dielectric platform which is 100 per cent Pb-free, RoHS and REACH-compliant without exemptions. They are low profile and exhibit low inductance and ESR with respect to application frequency, allowing for very high ripple current capability.
