Kemet has expanded its range of metallised polypropylene film EMI suppression capacitors with the R53B series. They are designed to operate reliably at temperatures up to 125°C and meet UL94V-O specifications thanks to an envelope of self-extinguishing resin in the housing.
Target applications include capacitive power supplies, three-phase UPS, smart metering and microinverters for solar applications. They also suit automotive applications like on-board chargers. The capacitors are available in tape and reel packaging according to IEC 60286-2.
The R53B series relies on X2 technology which combines THB class IIIB, miniaturized dimensions, high capacitance value and low halogen content. They also meet the requirements for climate class 40/110/56, IEC 60068-1, are AEC-Q200 certified and RoHS compliant.
Capacitance ranges from 0.068 to 20μF at a recommended DC voltage of ≤1000VDC and a rated AC voltage of 350VAC 50/60Hz or rated DC voltage of 800VDC. Service life is 1,000h at -40 to 125°C.
