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 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 Specifi cations - 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 with Ripple 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 Dimensions Construction Details Tin Plated Steel or Case Material Oval Case Style Round Case Style Aluminum Encapsulation Enviromentally Safe Dielectric Fluid Tin Plated Steel Terminal Material Note: The capacitors 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.
