**- Type SF Motor Run and Power Supply Capacitors Oil Filled/Impregnated, AC Rated, Metallized Polypropylene 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 motorrun 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

**Capacitance Range Capacitance Tolerance Rated Voltage Operating Temperature Range Dissipation Factor Service Life Objective** 

5.0 µF to 120.0 µF ±10% standard, ± 6% and ±3% available 240 Vac to 660 Vac –40 ºC to 70 ºC standard, 90 ºC available <0.1% 60,000 h with 94% survival rate **RoHS Compliant** 

## **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. 

## **Capacitance vs. Temperature** 

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

*Note: The capacitor’s safety pressure interrupter is designed to disconnect the capacitor element as the cover expands upward due to gas pressure build up. Catastrophic failure may result if movement of the cover and or terminals are restricted.  Rigid bus bars are not recommended as they may restrict movement of the cover or terminals. Customers are advised to provide at least 0.5” clearance above the cover to allow for its expansion.
