New Vishay Automotive DC-Link Film Capacitors

Delivers Stable Capacitance and ESR in High Humidity Environments

Vishay Intertechnology introduces 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 — 85C, 85% relative humidity for 1000 hours at rated voltage —without altering its electrical characteristics. Designed to ensure extremely stable capacitance and ESR values over a long service life under harsh environmental conditions during operation.

The Key Specifications:

• Rated capacitance: 1 μF to 80 μF
• ESR: 3.0 mΩ to 24.8 mΩ
• Ripple current: 4.5 A to 25.1 A
• Rated voltages at +85C: 500 VDC, 700 VDC, 800 VDC, 920 VDC, and 1200 VDC

Features:

• AEC-Q200 qualified
• Withstand THB testing at 85C, 85 % relative humidity for 1000 hours at rated voltage
• Low ESR down to 3 mΩ
• High ripple current capabilities up to 25.1 A
• Five rated voltages from 500 VDC to 1200 VDC at +85C
• RoHS-compliant, halogen-free, and Vishay GreenMarket

Applications:

• 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

Availability: Samples of the MKP1848H DC-Link series are available now with a lead time of 20 weeks for production quantities.
