Aluminum Can Power Film Capacitors
C44P-R, 330 – 1,000 VAC/700 – 2,300 VDC,
for PFC & AC Filter
Overview
The C44P-R capacitor is a polypropylene metallized film
capacitor with a cylindrical, aluminium can-type design filled
with a soft, vegetable oil-based, polyurethane resin. It uses
screw terminals, a plastic insulator, and an overpressure
safety device.
Applications
Typical applications include commutation, power factor
correction, and AC harmonic filtering.
