High-temperature film capacitor for automotive applications

The metallised polypropylene DC-Link film capacitors of the MKP1848e series from Vishay are now expanding Rutronik's portfolio. The components combine high operating temperatures of up to 125C, AEC-Q200 qualification and high robustness under high humidity - excellent for automotive HVDC systems. Thanks to its high packaging density, low ESR/ESL, and excellent current characteristics, the series provides DC filtering with superior dimensional and electrical properties.

The new series addresses the more stringent requirements for automotive high-voltage applications. The components are qualified in accordance with AEC-Q200 (rev. E) and Vishay Automotive Grade and can withstand 125C for 500 hours over the component's lifetime while maintaining excellent electrical stability.

The high humidity and temperature resistance, in accordance with THB Grade III (IEC 60384-16 Ed. 3), allows them to be used in harsh environments, withstanding 60C and 93% relative humidity at UNDC for over 56 days (1,344 hours).

The voltage range extends up to 1,300VDC at 85C, which allows use in 800VDC HV vehicle electrical systems at 125C. The capacitors are mounted radially, allowing for alternative connection options. The high-density packaging reduces the size of the component by up to 40% compared to previous Vishay automotive DC-Link generations while allowing higher ripple currents for similar component volumes.

Typical applications include major EV / PHEV power electronic devices in eMobility and industrial power conversion.
