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 Specifications Click here to view hardware - 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 Capacitance Range 5.0 F to 120.0 F Capacitance Tolerance 10% standard, 6% and 3% available Rated Voltage 240 Vac to 660 Vac Operating Temperature Range -40 C to 70 C standard, 90 C available Dissipation Factor <0.1% Service Life Objective 60,000 h with 94% survival rate RoHS Compliant Service Life Objective Capacitance vs. Temperature 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. 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.
