This capacitor is used for start-up and operation of AC motors, such as Motor Run or Heat Pump Air Conditioner or Condenser Straight Cool.It is small in size, lightweight, heat resisting and anti-explosion. Model: CBB65(Universal model). Case Material: unpainted aluminum case. Dielectric Material: metallized polypropylene film. Available Capacitance: 35+5uf. Capacitance Tolerance:±6%. Operating temperature: -40℃ to +70℃/-40℉ to +158℉. Frequency:50/60 Hz. Operating Life:60,000 hours with 94% survival. Dissipation Factor:0.1% maximum. A PRIME CLUB ac capacitor can be used in place of a 370 volt capacitor and a 440 volt capacitor. A capacitor is an electric component that temporarily stores an electrical charge. A dual "run capacitor" supports two electric motors, such as in large air conditioner or heat pump units, with both a fan motor and a compressor motor. It saves space by combining two physical capacitors into one case. The dual capacitor has three terminals labeled C, FAN, and HERM, Herm/H for the compressor motor, Fan/F for the fan, and C for the common line.
