What does the name of the capacitor mean (2)

The names and functions of capacitors in different circuits Capacitors are an energy storage element. In order to recognize and identify capacitors in different circuits, people have given them many names according to their functions in the circuit. Life is still very helpful.

1. The step-down current-limiting capacitor is connected in series in the AC circuit to help it divide the voltage and limit the capacitive reactance of the AC power.

2. The shortened capacitor is a capacitor connected in series in order to shorten the length of the oscillating inductance coil in the UHF tuner.

3. Clapper capacitor is a capacitor connected in series to the oscillating coil in the capacitor three-point oscillation circuit, in order to eliminate the influence of the transistor junction capacitance and improve the frequency stability.

4. The Sila capacitor is in the capacitor three-point oscillation circuit, and is connected to the capacitor at both ends of the oscillation coil. In order to eliminate the influence of the transistor junction capacitance, the higher the oscillation frequency, the easier it is to vibrate.

5. The acceleration capacitor is connected to the oscillator feedback circuit to accelerate the positive feedback process and increase the oscillation amplitude.

6. Pre-emphasis capacitors In order to prevent the audio modulation signal from attenuating or losing the high-frequency components during modulation, the capacitors in the RC network of the high-frequency components are appropriately increased.

7. The de-emphasis capacitor attenuates the part of the high-frequency component in the audio signal that has been enhanced by pre-emphasis together with the noise, and restores the original appearance of the audio signal. The capacitor in the RC network.

8. The amplitude stabilization capacitor is used in the frequency discriminator to stabilize the output signal amplitude.

9. Capacitor for eliminating bright spots In the auxiliary circuit of the kinescope, it is used to eliminate the capacity of bright spots during shutdown.

10. The phase-shift capacitor is used to change the phase of the AC signal.

11. Feedback capacitor A capacitor used to feedback the signal across the input and output terminals of the preamplifier.

12. The soft-start capacitor is usually connected to the base of the power switch to prevent the switch from being damaged by too much surge current or voltage applied to the base of the switch when it is turned on.

13. The starting capacitor is connected in series with the secondary winding of the single-machine motor to provide the secondary winding of the motor with phase-shifted AC current for starting. When the motor is running normally, it is disconnected from the secondary winding.

14. The running capacitor is connected in series with the secondary winding of the stand-alone motor to provide phase-shifted AC current for the secondary winding of the motor. When the motor is running normally, it is still in series with the secondary winding in the circuit.
