Type SM Motor-Run and Power Supply Capacitors
Metallized Polypropylene
Applications
Motor Run Capacitors — provide starting torque
and power factor correction for split phase motors
typically used in refrigeration and air conditioning.
Power Supply Capacitors — are used in power
supply circuits to provide noise suppression, volt-
age regulation, and line current reduction.

% of Rated Voltage
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 spe-
cific conditions of temperature and voltage by using
the curves as shown to the right.

Capacitance vs.Temperature
The Capacitance vs. Temperature curve may be
used to determine the capacitance change as a func-
tion of temperature. Capacitance varies by no more
than ±3% over the operating temperature range.
