DC-Link Film Capacitors Deliver Stable Capacitance and ESR in High Humidity Environments

Vishay Automotive Grade DC-Link Film Capacitors Deliver Stable Capacitance and ESR in High Humidity Environments

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 altering 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.

Applications

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
• UPS

MKP1848H DC-Link series capacitors features

• rated capacitance from 1 µF to 80 µF
• low ESR down to 3 mΩ
• high ripple current capabilities up to 25.1 A
• rated voltages of 500 VDC, 700 VDC, 800 VDC, 920 VDC, and 1200 VDC at +85 °C.
• RoHS-compliant
• halogen-free and Vishay Green.

Samples of the MKP1848H DC-Link series are available now. Production quantities will be available in Q3 2020 with a lead time of 20 weeks.
