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. 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.
-
3. Can ceramic capacitors be used in AC?
Ceramic capacitors are well suited for AC circuits because they have good frequency response characteristics and low losses.
-
4. Why are mica capacitors so expensive?
Mica capacitors are expensive because of their excellent electrical properties (such as very low dissipation factor and stable temperature coefficient) and their high production costs.
