SMF : Polypropylene Capacitor: 160Vdc - 1500Vdc, 110Vac - 660Vac
Polyester Capacitor: 63Vdc - 630Vdc, 110Vac - 250Vac

Polypropylene and polyester power capacitors with very low inductance.

Product description

SMF capacitors are designed for use in circuits requiring low loss, low inductance and high RMS currents. For ease of mounting the range is available with M8 electro-tinned brass terminals. The terminals can be optionally male (stud) or female (bush). The terminals allow very close connection to the capacitor end spray minimising inductance making these capacitors very suitable high frequency switching in inverters, resonant circuits, 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.

Polypropylene SMF capacitors are additionally available for 750Vdc, 1000Vdc, 1500Vdc, 500Vac and 660Vac, please contact us and we will be please to offer assistance.
