EMI suppression capacitors provide steady performance at high requirements

KEMET's R41B film capacitor series adds to Rutronik's product portfolio. The capacitors have voltage ratings of 350VAC (rated voltage) and up to 1500VDC (rated DC voltage) and passed 1,000 hours of operation at rated voltage applied in the accelerated THB test at temperatures of 85C and humidity of 85%. They provide an excellent solution to harsh environments usage and are also offered in a halogen-free version on request.

The film capacitor range with protection class Y2/X1 is currently the first on the market to combine THB class IIIB with high operating temperature and high capacitance value while supplying the smallest lead space of a minimum of 10mm. The capacitors are metallised polypropylene film coated with self-extinguishing resin and are UL/ENEC/CQC certified. They are used in a capacitance range of 2.2nF to 1.2µF and deliver a high-temperature capability of up to +125C. In addition, they are AEC-Q200 compliant and intended for usage in filters to suppress electromagnetic interference in "line-to-ground" (Y-capacitor) and "cross-the-line" (X-capacitor) applications.

Target applications include HVDC filters, 5G SMPS, automotive industry, DC-DC and DC/AC converters, solar inverters and energy storage.
