Capacitor Run 40UF is engineered to deliver stable and efficient electrical performance in a wide range of applications including single-phase electric motors, air conditioning units, compressors, fans, and other industrial machinery. With a capacitance of 40 microfarads (µF), typical voltage ratings from 240V up to 450V AC, and a tolerance of ±5%, this run capacitor is ideal for maintaining smooth motor operation and extending equipment lifespan123. Its cylindrical, non-polarized design—commonly constructed from robust polypropylene film or aluminum—ensures long service life and resistance to heat, vibration, and moisture. Run capacitors like the 40UF model are commonly used to improve power factor, reduce energy consumption, and facilitate efficient motor starting and running for both residential and industrial applications.
