Metallized Polypropylene Film Capacitors - R53B Series

KEMET's R53B series capacitor is constructed of metalized polypropylene film and encapsulated with self-extinguishing resin that meets the requirements of UL 94 V-0. The R53B series is used worldwide in electromagnetic interference (EMI) suppression in across-the-line applications that require X2 safety classification. They are intended for use in situations where capacitor failure would not result in exposure to electric shock. Typical applications include connection in series with the mains, capacitive power supplies, and energy meters, with special emphasis in automotive applications for severe ambient conditions such as on-board chargers.
