A capacitor is an electronic component that holds and releases electrical charge. The basic working principle of capacitors is charging and discharging, and of course rectification, oscillation and other functions. In addition, the structure of the capacitor is very simple, mainly composed of two positive and negative electrodes and an insulating medium sandwiched in the middle, so the type of capacitor is mainly determined by the electrode and the insulating medium. There are many uses of capacitors, mainly as follows:

one Dc isolation: The function is to prevent the DC through and let the AC through.

2. Bypass (decoupling) : Provides a low-impedance path for certain parallel components in an AC circuit.

3. Coupling: As a connection between two circuits, allowing AC signals to pass through and be transmitted to the next level of electricity

4. Filtering: This is very important for DIY, the capacitors on the graphics card are basically this role.

5. Temperature compensation: For the impact of the insufficient adaptability of other components to the temperature, and compensation to improve the stability of the circuit.

6. Timing: The capacitor is used in conjunction with the resistor to determine the time constant of the circuit.

Seven. Tuning: Systematic tuning of frequency-dependent circuits, such as cell phones, radios, and television sets.

8. Rectifier: Turning on or off a semi-closed conductor switch element at a predetermined time.

9. Energy storage: Storing electrical energy for release when it is needed. Such as camera flash, heating equipment, etc. Today, some capacitors are approaching the level of lithium-ion batteries, and a capacitor can store enough energy to power a mobile phone for a day.
