Vishay Intertechnology, Inc introduced a new low profile, humidity robust, AEC-Q200 qualified automotive DC-Link metallized polypropylene film capacitor.
Designed to meet the demands of high humidity automotive applications, the Vishay Roederstein MKP1848Se DC-Link is the first such device to withstand temperature humidity bias (THB) testing of 60 °C / 93 % relative humidity for 56 days at rated voltage.
The Automotive Grade capacitor released today is available in four building heights — 12 mm, 15 mm, 18 mm, and 24 mm — and 12 standard dimension options. With its low profile design and high resistance to humidity, the radial device is ideal for space-constrained automotive applications, including HVAC systems, on-board and inductive battery charging systems, air conditioning compressors, and motor drives for electric (EV) and plug-in hybrid electric vehicles (PHEV).
The MKP1848Se DC-Link capacitor offers rated capacitance from 1 µF to 75 µF and low ESR down to 3 mΩ. The RoHS-compliant device provides high ripple current capabilities up to 27 A and rated voltages of 500 VDC, 700 VDC, 900 VDC, and 1200 VDC at +85 °C.
