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

Service Life Objective
The service life objective for this series is 60,000 hours of
operating life with a 94% survival rate when operated at full
voltage, 60 Hz, and rated ambient temperature. AC
capacitors are frequently used at voltages and ambient
temperatures other than rated conditions. Service life may
be estimated under specific conditions of temperature and
voltage by using the curves as shown
below and
to the right.
Capacitance vs. Temperature
The Capacitance vs. Temperature curve may be used to
determine the capacitance change as a function of
temperature.
Capacitance
varies by no more than ±3 % over
the operating temperature range.
