Metal film caps operate in harsh environments

Kemet has developed a new series of metallized polypropylene film capacitors that can operate in harsh environments and EV applications

By Gina Roos, editor-in-chief

Kemet Corp. has launched the R41T and R76H series AEC-Q200–qualified metallized polypropylene film capacitors for use in automotive applications, including electric vehicle (EV) powertrains and advanced driver-assistance systems (ADAS).

The R41T and R76H capacitors offer a 125°C maximum operating temperature and exceed the requirements of 85°C/85% relative humidity temperature-bias-humidity tests. These capacitors also support the design of high-performance, high-reliability circuits, including wide-bandgap (WBG) semiconductor solutions.

“The new technology employed in our R41T and R76H and metallized polypropylene film capacitors ensures a high level of electrical performance along with industry-leading levels of ruggedness and reliability,” said Dr. Philip Lessner, Kemet senior vice president and chief technology officer, in a statement. “With silicon approaching the limits of its development, the WBG market is expected to grow significantly, reaching a forecasted $1,820 million in 2024 — an increase of 33.4% over a five-year period.”

The R41T and R76H capacitors are available via KEMET distributors.
