Vishay Intertechnology Automotive Grade DC-Link Film Capacitors Deliver Stable Capacitance and ESR in Harsh Environments

September 10, 2020 Tiera Oliver

Vishay Intertechnology introduced a new series of Automotive Grade DC-Link metallized polypropylene film capacitors optimized 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 are designed to ensure 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 VDC, 700 VDC, 800 VDC, 920 VDC, and 1200 VDC at +85 °C. The capacitors are RoHS-compliant, halogen-free, and Vishay Green.

Samples of the MKP1848H DC-Link series are available now. Production are available with a lead time of 20 weeks.
