The JFQF series by jb Capacitors is a high-reliability AC filter capacitor designed for industrial-grade filtering applications, especially in UPS inverters and solar photovoltaic DC/AC systems using LCL filter topology.
Built with metallized polypropylene film, the JFQF offers outstanding self-healing performance, ensuring long-term electrical stability under high stress. It features high ripple current endurance, excellent dv/dt withstand capability, and consistently low ESR and ESL values. Encased in a flame-retardant plastic shell (UL 94V-0), it provides excellent insulation and thermal resistance.
