KEMET R71 Series - Single Metallized Polypropylene Film Capacitors
The KEMET R71 series are single metallized polypropylene film capacitors with radial leads, designed for pulse and high-frequency applications, including SMPS and PFC. They feature a self-healing mechanism, a self-extinguishing, solvent-resistant plastic case meeting UL 94 V-0 requirements, and RoHS compliance with lead-free terminations. These capacitors offer a wide voltage and capacitance range, suitable for demanding power factor correction and pulse applications.
