Functions of Ceramic Capacitors

I. Functions of Ceramic Capacitors

  1. DC Isolation: Prevents the passage of direct current while allowing alternating current to flow.
  2. Bypass (Decoupling): Provides a low-impedance path for certain parallel components in an AC circuit.
  3. Coupling: Connects two circuits, allowing AC signals to pass through and transmit to the next circuit.
  4. Filtering: Particularly crucial for DIY projects, where capacitors on graphics cards often serve this purpose.
  5. Temperature Compensation: Compensates for the inadequate temperature adaptability of other components, improving circuit stability.
  6. Timing: Used in conjunction with resistors to determine the time constant of a circuit.

II. Advantages of Ceramic Capacitors

  1. High-voltage ceramic capacitors exhibit stable capacitance loss with temperature and frequency.
  2. The special series structure of high-voltage ceramic capacitors is suitable for reliable long-term operation at high voltages.
  3. High-voltage ceramic capacitors have a high current rise rate and are suitable for high-current circuits with non-inductive structures.

In Conclusion

The above outlines the functions and advantages of ceramic capacitors. I hope this information proves helpful to you.
