Energy Storage Capacitors

Energy storage capacitors for pulse power, high voltage applications are available from PPM Power. The capacitors are not limited to a catalogue range and current, voltage, size, mass and terminations are matched to the customer’s requirement and application.

High reliability 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. High conductivity copper is used for low resistance internal connections.

Capacitors are finished in powder coated corrosion free metal or insulated cases and filled with an environmentally safe oil or dry leak free resin.
