Service Life Objective

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 specific conditions

of temperature and voltage by using the curves as shown

below and to the right.

Motor-Run and Power Supply 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.

Highlights

• Self healing

• Fault current protection up to 10,000 amps AFC

• Low energy consumption

• 4 - tine, 1/4” quick connect lug terminals are standard

• Meets EIA Standard EIA-456-A

• UL recognized File Number E71645

• CSA File Number 223507
