IGBT snubbers capacitors

Alcon IGBT snubbers capacitors MP-4, MP-4A, KPF and KPF-9 are designed for high power convertors and use a low loss dielectric of polypropylene film. The capacitors with double metallised plastic film electrodes and with metallised polypropylene as a quasi electrode with an internal series construction are designated MP-4 and MP-4A. These are recommended for low and medium pulse application. Capacitors designed for extremely high pulse applications have aluminium foil as electrodes and have a metallised polypropylene quasi electrode with an internal series construction. These capacitors are designated KPF and KPF-9. The MP-4, MP-4A, KPF and the KPF-9 capacitors have self healing properties. Another type of capacitors are designated KP-3C. These capacitors are unique since they have extended aluminium foil electrodes with polypropylene film dielectric and are impregnated. This design is not only suitable for IGBT protection circuits and snubber networks but can also be effectively used in low and medium frequency tuning / resonant circuits.

The Alcon range of IGBT snubber capacitors are ROHS and REACH compliant. Flame retardant characteristics are ensured by use of plastic enclosure and epoxy end fill which conform to UL94-VO. A total 24 terminal styles and 35 case sizes are available as a standard. In addition custom designed capacitors are also available.
