DC Capacitors

Suitable for most demanding applications

API Capacitors design and manufacture a large range of standard and custom designed DC capacitors. GD Rectifiers works with API to offer customers a tailor-made DC capacitors, the current, voltage, size, mass and terminations are matched to the customer’s requirement and application. Long life and high reliability for DC capacitors is achieved using ultra low defect density, high isotactic, metallised polypropylene dielectric film incorporating an extended working temperature range and controlled self-healing capability. Elements are wound on the latest precision edge controlled automatic winding machines. API Capacitors use high conductivity copper for low resistance internal connections. The DC capacitors are finished in powder coated corrosion free metal or insulated cases and filled with an environmentally safe oil or dry leak free resin.
