Automotive Grade DC-Link Metalized Polypropylene Film Capacitors for High Humidity Environment
Vishay Intertechnology, Inc. has introduced the MKP184H DC-Link, a new series of Automotive Grade DC-Link metalized polypropylene film capacitors for high humidity environment. Theses new capacitors are designed to ensure extremely stable capacitance and ESR values over a long service life even under harsh environmental conditions during operation. The MKP184H DC-Link is the Vishay’s first series of AEC-Q200 Qualified DC-Link film capacitors that can withstand temperature humidity bias testing (85°C, 85% relative humidity for 1000 hours at rated voltage) without altering its electrical character.
The MKP184H DC-Link comes with a rated capacitance ranging from 1 µF to 80 µF and a low ESR down to 3 mΩ. With a high ripple current capability of up to 25.1A, the devices have a rated voltage of 500 VDC, 700 VDC, 800 VDC, 920 VDC, and 1200 VDC at +85 °C. More technical details can be found in the datasheet linked below.
The high robustness of the device makes them 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.
