jb motor starting capacitors

Start capacitors briefly increase motor starting torque and allow a motor to be cycled on and off rapidly. Start capacitors have ratings above 70 microfarads (µF), with three major voltage classifications: 125 V, 250 V, and 330 V. A start capacitor stays energized long enough to rapidly bring the motor to 3/4 of full speed and is then taken out of the circuit, such as by a centrifugal switch that releases when rotating at or around that speed.

JFS - Motor Starting Capacitor

Examples of motor capacitors are: a 35 µF, at 370 V, run capacitor, or an 88–108 µF at 250 V start capacitor.

jb have the motor starting capacitors of capacitance range 1uF~20uF(JFS-A~D、JFS-5~7、JFS-9) 1uF~100uF(JFS-11~18).

What is Capacitance ?

The capacitance of certain capacitors decreases as the component ages. In ceramic capacitors, this is caused by degradation of the dielectric. The type of dielectric and the ambient operating and storage temperatures are the most significant aging factors, while the operating voltage has a smaller effect.

The aging process may be reversed by heating the component above the Curie point. Aging is fastest near the beginning of life of the component, and the device stabilizes over time,electrolytic capacitors age as the electrolyte evaporates. In contrast with ceramic capacitors, this occurs towards the end of life of the component.

Our jb capacitors has various capacitance.Such as our JFA-Mylar Polyester Film Capacitors, capacitance range from 0.001 to 0.47μF.
