Vishay Intertechnology has introduced a new series of Automotive Grade DC-Link metallised polypropylene film capacitors optimised for high humidity environments.
The Vishay Roederstein MKP1848H DC-Link is Vishay’s first series of AEC-Q200 qualified DC-Link film capacitors to withstand temperature humidity bias (THB) testing − 85°C, 85% relative humidity for 1000 hours at rated voltage, without alteration of its electrical characteristics.
The radial capacitors released today are designed to ensure extremely stable capacitance and ESR values over a long service life under harsh environmental conditions during operation. The robust devices are ideal for output filtering in automotive on- and off-board chargers and DC/DC converters; power converters for solar farms; auxiliary power supplies in wind energy generators; industrial power supplies and motor drives; welding equipment; and UPS.
MKP1848H DC-Link series capacitors offer rated capacitance from 1 µF to 80 µF and low ESR down to 3 mΩ. The devices provide high ripple current capabilities up to 25,1 A and rated voltages of 500 V d.c., 700 V d.c., 800 V d.c., 920 V d.c. and 1200 V d.c. at 85°C. The capacitors are RoHS-compliant, halogen-free and Vishay Green.
