1. Ceramic Capacitors (CC)Basic Introduction:Ceramic capacitors use ceramic material as the dielectric, offering excellent dielectric properties and stability. The manufacturing process involves stacking metal electrodes with ceramic layers, followed by polarity marking and packaging.Applications:In the PCB industry, ceramic capacitors are commonly used in high-frequency circuits and noise filtering circuits. Known for low loss, low distortion, and high-frequency response, they are suitable for RF filters, power coupling, and decoupling applications.Pros and Cons:Pros:1. Excellent high-frequency performance suitable for high-frequency circuits.2. Small size and light weight, suitable for space-constrained circuit designs.3. Good high-temperature stability, ideal for high-temperature operating environments.Cons:1. Relatively small capacitance, unsuitable for circuits with large capacitance requirements.2. Limited operating voltage range, not suitable for high-voltage applications.
