Vishay MKP1848e 500–1300V Automotive DC-Link Capacitors
Manufacturer: Vishay Roederstein
Package / Case: Radial plastic case with two or four pins
Description: AEC-Q200 qualified high-temperature polypropylene DC-link film capacitor rated from 500 VDC to 1300 VDC
The Vishay MKP1848e is designed for demanding DC-link filtering in electric vehicles, charging systems and industrial power converters. Its metallized polypropylene construction combines low losses, high ripple-current capability and stable electrical performance without the wear-out mechanism associated with liquid-electrolyte capacitors.
The series is particularly useful in high-temperature environments where conventional polypropylene DC-link capacitors may be limited by a +105°C maximum hot-spot temperature.
