API Capacitors offer a wide range of snubber capacitors for GTO, IGCT and other thyristor devices. Current, voltage, size, mass and terminations are matched to the customer’s requirement and application, a few of which are listed below.

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.

Custom Design Capacitors

Designed to meet detailed or brief specifications. Our technical sales representatives can work closely with your design team at concept stage or at the later stages of a project when a time critical design is needed. Alternatively like for-like replacements for older retrofit designs can be offered.
