Type SF Motor-Run and Power Supply Capacitors
Oil Filled/Impregnated, AC Rated, Metallized Polypropylene Capacitors
Type SF, AC rated metallized polypropylene capacitors provide
starting torque and power factor correction for split phase
motors typically used in refrigeration and air conditioning motor-
run applications. Type SF also may be used to provide noise
suppression, voltage regulation and line current reduction in power
supply applications.

Note: The capacitor’s safety pressure
interrupter is designed to disconnect
the capacitor element as the cover
expands upward due to gas pressure
build up. Catastrophic failure may
result if movement of the cover and
or terminals are restricted. Rigid bus
bars are not recommended as they
may restrict movement of the cover
or terminals. Customers are advised to
provide at least 0.5” clearance above
the cover to allow for its expansion.
