Type SF Dual, Round & Oval, Oil-Filled Motor Run Capacitors
Part Numbering System
Metallized Polypropylene Type SF dual rated oil filled motor run capacitors
made with self-healing metallized polypropylene lm
are commonly used in air conditioning, motors and
compressor applications. The dual ratings in a single
can provide two capacitors - one may be used as a fan
capacitor and the other as a compressor or motor run
capacitor. Three terminals allow one terminal to act as
a common while the other two are connected to the
individual capacitors.
The service life objective for the 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 specic conditions
