Single Run Capacitor, Oval, 5/440 uF

Jard 5 µF Oval Motor Run Capacitor – 440V AC, Metallized Polypropylene Film

The Jard 12929 Oval Run Capacitor is a fixed-value, single-section capacitor engineered for continuous-duty single-phase AC motor applications. It delivers a stable 5 microfarads of capacitance at 440 volts AC, making it ideal for use in fractional horsepower motors such as blower motors, condenser fan motors, and other HVAC inductive loads.

Manufactured with metallized polypropylene film and housed in a sealed aluminum case, the Jard 5 µF capacitor provides thermal stability, electrical consistency, and mechanical durability. It includes standard ¼-inch male quick-connect terminals and features an internal pressure interrupter for fail-safe operation.
