Snubber Capacitors
Offering a custom and standard snubber capacitor range including GTO protection capacitors, GCT protection capacitors and ZC thyristor snubber capacitors.
Snubber Capacitors
Power capacitors you can rely on
API Capacitors offer a wide range of standard and custom designed snubber capacitors for GTO, IGCT and other thyristor devices. We work together to customise current, voltage, size, mass and terminations ensuring these are matched to customer requirements and applications.
Long life and high reliability is achieved using ultra low defect density, high isotactic, metallised polypropylene dielectric film incorporating an extended working temperature range and self-healing capability. High current carrying capability is achieved with snubber capacitors using low resistance foil electrodes. Snubber capacitors are impregnated with an environmentally safe oil then finished in an insulated polymer case or encapsulated in resin.
Alternatively, leak free dry solutions are available, please let us know if you would prefer this option.
API’s standard snubber capacitor range includes GTO protection capacitors, GCT protection capacitors and ZC thyristor snubber capacitors.
