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 - CSA File Number 223507 Specifications Capacitance Range 5.0 µF to 120.0 µF Capacitance Tolerance ±10% standard, ± 6% and ±3% available Rated Voltage 240 Vac to 660 Vac Operating Temperature Range –40 ºC to 70 ºC standard, 90 ºC available Dissipation Factor <0.1% Service Life Objective 60,000 h with 94% survival rate RoHS Compliant Dimensions Click here to view hardware Oval Case Style Construction Details Case Material Round Case Style .81" ± .06" .81" ± .06" Aluminum or Tin Plated Steel Encapsulation Enviromentally Safe Dielectric Fluid Terminal Material Tin Plated Steel A ± .06" B ± .06" Case Code A B C D A 1.31 1.56 1.91 1.97 D ± .06" .50" Max. .50" Max.

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. H See Ratings Table CDE Cornell Dubilier • 1605 E.
