PC : Polypropylene Capacitor: 160Vdc - 700Vdc, 110Vac - 250Vac
Polyester Capacitor: 63Vdc - 630Vdc, 110Vac - 250Vac

Polypropylene and polyester power capacitors house in aluminium cans for ease of configuration.

Product description

PC capacitors are designed for use in power electronic circuits requiring low loss, good environmental capability, flexibility of design and easy mounting. The range is available with or without a base mounting stud on the can. The electrical connections can be offered as screws or flying leads. These capacitors very suitable for use in inverters, filtering and energy storage in switched mode power supplies (SMPS).

The capacitors can be designed in a wide variety of configurations to optimise size, ripple current rating and temperature rise, if you have a specific requirement or query then please contact us. Detailed ripple current ratings and temperature rise estimates are available on request.
