Uses and Functions of Typical Ceramic Capacitors (II)

3) Smoothing

The smoothing capacitor is used to suppress the pulse generated on the rectified power circuit and smooth the signal so that it is closer to DC. If a smoothing capacitor is inserted after rectification, the capacitor can be stored at high voltage and discharged at low voltage, effectively suppressing voltage fluctuations.

4) Filter

By combining a capacitor, a resistor, and an inductor, a filter that passes only a specific frequency signal can be made. The filter is divided into a low bypass filter that takes out only low frequency components and a high bypass filter that takes out only high frequency components, and can be used separately depending on the required frequency.
