DC-Link Film Capacitors Deliver Stable Capacitance and ESR


AEC-Q200-Qualified Metallized Polypropylene Devices Withstand THB Testing

Vishay Intertechnology, Inc. 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 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 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. Pricing for U.S. delivery only starts at $1.00 per piece.
