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 film 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 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 volt-
age by using the curves below.
