Thyristor, GTO and IGCT Snubber Capacitors
A wide range of snubber capacitors for GTO, IGCT and other thyristor devices are available from PPM Power. Current, voltage, size, mass and terminations are matched to the customer’s requirement and application.
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 using low resistance foil electrodes. 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.
