CBB61 0.6uF, 0.75uF, 1uF, 1.2uf, 1.5uF, 1.8uF, 2uF, 2.5uF, 3uF, 3.5uF, 4uF, 4.5uf, 6uF, 8uF, 10uF, 12uF, 15uF, 20uF 450V AC, 50/60Hz Fan Starting Capacitor For Ceiling Fan, Exhaust Fan, Dynamo-motor, Hood Fan Capacitor CBB61 AC motor run capacitor can be used in an electric motor under lower starting electric current. It helps to produce higher starting torque. It is commonly used in in single phase motor/fan. Features: Capacity: 0.6uF, 0.75uF, 1uF, 1.2uf, 1.5uF, 1.8uF, 2uF, 2.5uF, 3uF, 3.5uF, 4uF, 4.5uf, 6uF, 8uF, 10uF, 12uF, 15uF, 20uF The capacitor achieves this by lagging the current which is connected to the second phase for starting. Having a larger value capacitor will enable more current to flow due the lower impedance. Having slightly less impedance will mean you have slightly more voltage drop across the motor. Given the motor is mains rated this will never pose a problem.

Suitable for starting and running for mono- or single phase motors with power supply AC 50/60Hz Rated at 450V AC rated voltage Most capacitors are labeled with tolerances. You will find the AC motor start capacitors that you are using are typically +/- 20%. That means the recommended 12 μF capacitor can be as high as 14.8 μF and as low as 9.6 μF.

A capacitor stores potential electrical energy for use later. It is a passive component with two conductors - positive and negative, which are insulated from each other. Capacitors help reduce voltage pulsation to certain electrical devices. The purposes of the capacitor is create a second phase to help one phase AC asynchronous motors start (instead of pulsating you get a rotating magnetic field). Once the motor has started rotating the capacitor is no longer required as these motors can, and do, operate off one phase. Used for range of applications: Ceiling Fan, Exhaust Fan, Dynamo-motor, Hood, Washing Machine, Home Appliance etc. And then the start cap shuts down, replaced by run caps, to maintain the electrical load required to maintain the motor.
