1. Why are ceramic capacitors better?

Small size: suitable for high-density circuit board design.
Good temperature resistance: can work over a wide temperature range.
High reliability: no electrolyte, so it is not easy to age.
Good frequency response: suitable for high-frequency applications.
Low ESR: low equivalent series resistance, which helps to improve efficiency.
2. Is ceramic capacitor AC or DC?

Ceramic capacitors can be used in both AC and DC circuits. They have no polarity, so they can be installed at will.
3. Do ceramic capacitors deteriorate over time?

While ceramic capacitors are relatively stable, their capacitance value may decrease slightly over time, especially under extreme environmental conditions. However, this change is usually small and will not significantly affect most applications.
4. Does the voltage of ceramic capacitors matter?

Voltage ratings are critical to ensure safe operation. Using a capacitor below the rated voltage may cause premature failure; using a capacitor above the rated voltage may cause immediate damage.
