WIMA FKP 1 Polypropylene (PP) Capacitors for Pulse Applications

The WIMA FKP 1 series offers high-performance polypropylene (PP) capacitors specifically designed for pulse applications. Featuring metal foil electrodes and an internal series connection, these capacitors provide extremely high pulse duty, self-healing capabilities, and a very low dissipation factor. They are ideal for high pulse and high-frequency applications such as switch mode power supplies, converters, deflection systems, and electronic ballasts.
