Capacitor is a kind of electronic components used in a large number of electronic devices, which should be widely used in circuit isolation through cross, coupling, bypass, filtering, tuning circuit, energy conversion, control and so on. About the role of capacitors, are you clear about it? The following amperometric capacitor Cucab will introduce the role of capacitors, capacitor manufacturers and prices, and other contents.
The basic working principle of capacitor is charging and discharging, of course, there are rectification, oscillation and other functions. In addition, the structure of capacitor is very simple, mainly composed of two positive and negative electrodes and insulating medium sandwiched in the middle, so the type of capacitor is mainly determined by the electrode and insulating medium. There are many uses of capacitors, mainly as follows
1. DC isolation: prevent the direct current from passing through and let the AC pass through.
2. Bypass (decoupling): To provide low impedance path for some parallel components in AC circuit. Safety capacitor
3. Coupling: As a connection between two circuits, allowing AC signals to pass through and be transmitted to the next level circuit. Ceramic capacitor

4. Filtering: This is very important for DIY, the capacitors on the graphics card are basically this role.
5. Temperature compensation: for other components to the temperature of the adaptability of the impact brought about by insufficient, and compensation, to improve the stability of the circuit.
6. Timing: capacitors are used in conjunction with resistors to determine the time constant of the circuit.
7. Tuning: system tuning of frequency-related circuits, such as cell phones, radios, televisions.
8. Rectifier: open or open half-closed conductor switching element at a predetermined time.
9、Energy storage: storage of electrical energy, used to release when necessary, such as camera flash, heating equipment, etc.
