Do absorption capacitors have positive and negative electrodes? What is the function of absorption capacitors？

Absorbing capacitor is a special type of capacitor commonly used in DC circuits. Unlike ordinary capacitors, absorption capacitors have positive and negative poles. Its main function is to reduce the impact of power fluctuations on the circuit.

1. The positive and negative poles of the absorbing capacitor
Absorption capacitors have positive and negative poles, so polarity should be taken into consideration when using them. If the connection is reversed, it may burn out the capacitor or other components. You can determine its polarity by checking the markings on the capacitor.

2. The function of absorbing capacitance
The main function of absorbing capacitors is to reduce the impact of power supply fluctuations on the circuit. When there is a large voltage and current surge in the circuit, the absorbing capacitor can absorb some energy, thereby protecting other components from damage. In addition, it can also assist in the operation of voltage stabilizing circuits and filtering circuits.
