Type SF Dual, Round & Oval, Oil-Filled Motor Run Capacitors
Metallized Polypropylene
Type SF dual rated oil filled motor run capacitors made with self-heal-
ing metallized polypropylene film are commonly used in air condition-
ing, 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 con-
nected 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 specific conditions of tempera-
ture and voltage by using the curves below.
Highlights
- Fault current protection up to 10,000 A
- Low energy consumption — <0.1% DF
- Self healing
- L recognized under E71645
- Meets EIA Standard EIA-456-A
- 60,000 hours life
15–5 µF to 80–10 µF
±10% standard (±6% and ±3% available)
370 Vac and 440 Vac
