Robust Metallized Polypropylene Devices Deliver Extremely Stable Capacitance and ESR in High Humidity Environments

MALVERN, Pa. — May 3, 2021 — Vishay Intertechnology, Inc.today introduced a new series of metallized polypropylene AC filtering film capacitors optimized for high humidity environments. Vishay Roederstein MKP1847C AC Filtering devices withstand demanding temperature humidity bias (THB) testing — 40 °C, 93 % relative humidity for 56 days at rated voltage — without altering their electrical characteristics.

The capacitors released today are designed to ensure extremely stable capacitance and ESR values over a long service life under harsh environmental conditions during operation. Compared to previous-generation devices, the MKP1847C AC Filtering series offers higher humidity robustness at a lower cost, while maintaining the same footprint. The robust devices are ideal for input and output filtering in UPS systems, renewable energy inverter grid interfaces, and welding equipment.

MKP1847C AC Filter series capacitors feature a wide capacitance range from 1 µF up to 70 µF, with tolerance down to ± 10 %, and rated voltages of 230 VAC, 250 VAC, 275 VAC, 310 VAC, and 350 VAC. The devices offers low self-inductance of < 1 nH per mm of lead spacing, high peak current capabilities up to 750 A, and high RMS current up to 26 A. Offered in a flame-retardant plastic case with a resin seal, the robust capacitors features a high operating temperature to +105 ºC.

Samples and production quantities of the MKP1847C AC Filtering series are available now, with lead times of 12 weeks.
