Type SF Motor-Run and Power Supply Capacitors
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.

Service Life Objective
The service life objective for this series is 60,000 hours of
operating life with a 94ꢀ survival rate when operated at
full voltage, 60 Hz, and rated ambient temperature. AC ca-
pacitors are frequently used at voltages and ambient tem-
peratures 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.
The Capacitance vs. Temperature curve may be used to determine
the capacitance change as a function of temperature. Capacitance
varies by no more than 3ꢀ over the operating temperature range.
