The metallized 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 125°C, AEC-Q200 qualification and high robustness under high humidity - ideal for automotive HVDC systems. Thanks to the high packaging density, the low ESR/ESL and excellent current characteristics, the series offers DC-filtering with superior dimensional and electrical properties. Typical applications include major EV / PHEV power electronic devices in eMobility, and industrial power conversion. The capacitors are available here.
With the new series, Vishay is addressing 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 125 °C 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 60 °C and 93 % relative humidity at UNDC over 56 days (1,344 hours).
The voltage range extends up to 1,300 VDC at 85 °C, which enables use in 800 VDC HV vehicle electrical systems at 125 °C. The capacitors are mounted radially and allow 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.
