Microfarad (MFD) is a term to describe a capacitor's level of capacity. That means the higher the microfarad rating, the more electrical current it can store. µF is symbol for microfarad.
Start capacitors briefly increase motor starting torque and allow a motor to be cycled on and off rapidly. A start capacitor stays in the circuit long enough to rapidly bring the motor up to a predetermined speed, which is usually about 75% of the full speed, and is then taken out of the circuit, often by a centrifugal switch that releases at that speed. Afterward the motor works more efficiently with a run capacitor.
Start capacitors usually have ratings above 70 µF, with four major voltage classifications: 125 V, 165 V, 250 V, and 330 V.
Run capacitors - Some single-phase AC electric motors require a "run capacitor" to energize the second-phase winding (auxiliary coil) to create a rotating magnetic field while the motor is running.
Run capacitors are designed for continuous duty while the motor is powered
