KEMET R53 and R58 EMI Suppression Capacitors are designed for situations where capacitor failure would not result in exposure to electric shock. The R53 miniature capacitors utilize X2 technology in terms of combined THB Grade 3B level and feature high capacitance density and high capacitance values in a small pitch. The R53 and R58 capacitors are constructed of metalized polypropylene film encapsulated with self-extinguishing resin in a box of material that meets the requirements of UL 94V-0. These capacitors are AEC–Q200 qualified, RoHS compliant, and operate within a -40°C to +110°C temperature range. Typical applications include LED drives, smart utility meters, solar micro-inverters, EMI filters in wireless power transfer, and consumer electronics.
The R53B capacitors are constructed of metallized polypropylene film encapsulated with self-extinguishing resin in a box of material that meets the requirements of UL 94V–0. R53B capacitors feature a high operating temperature rating of +125°C, power ratings of 350VAC and 800VDC, and low halogen content according to JS709C. Intended for use in situations where capacitor failure would not result in exposure to electric shock, R53B capacitors are ideal for harsh environmental conditions and meet the demanding Automotive Electronics Council’s AEC–Q200 qualification requirements.

R58 X1 Metallized Polypropylene Film EMI Suppression Capacitors are first-to-market X1 MKP technology-based capacitors designed to thrive in harsh environments with rated AC and DC voltages. These capacitors are expertly crafted from metalized polypropylene films and housed in a UL 94V-0 compliant enclosure, ensuring self-extinguishing resin protection with an extended operating temperature range of up to 110°C. The R58 capacitors find a wide range in EMI filter applications where X1 safety classification is required. Think energy storage, inverters, and the broader industrial sector, demanding high THB performance (Grade-IIIB) and robust current handling. Furthermore, R58 proves its mettle in automotive applications, particularly in HVDC EMI filters requiring voltages exceeding 800VDC.
