Analysis of the meaning of common capacitors in different circuits(IV)

22. Eliminate bright spot capacitance

In the auxiliary circuit of the picture tube, the capacitance to eliminate the bright spot is used.

23. Phase shift capacitance

A capacitor used to change the phase of an alternating current signal.

24. Feedback capacitance

A capacitor connected to the amplifier's input and output terminals for feedback signals.

25. Soft start capacitor

Normally, the power supply is switched on to the base of the power switch tube to prevent the switch tube from damaging the surge current or voltage at the switch base when it is switched on.

26. Starting capacitor

It is connected in series to the secondary winding of the single-phase motor, providing the phase shifted alternating current for the auxiliary winding of the motor, and when the motor is running normally, it is disconnected from the secondary winding.

27. Operation capacitance

It is connected in series to the secondary winding of the single-phase motor, providing the phase shifted alternating current for the secondary windings of the motor, and the secondary winding is still in the circuit in the normal operation of the motor.

28. AC safety gauge ceramic capacitor

It is used to prevent the interference of the antenna in the AC circuit of the electronic equipment, to prevent the noise of the power supply of the household appliances and so on, and to prevent the electrical products from electric shock and so on when the equipment fails.
