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. What is the difference between ceramic capacitors and electrolytic capacitors?
Polarity: Ceramic capacitors are non-polar, while electrolytic capacitors are polar.
Capacity range: Electrolytic capacitors generally offer larger capacitance values.
Stability: Ceramic capacitors are more stable, especially when the temperature changes.
Lifespan: Ceramic capacitors have a longer lifespan because there is no liquid electrolyte to dry out. -
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. Can I replace ceramic capacitors with film capacitors?
Film capacitors can be used to replace ceramic capacitors in some application scenarios, especially when better temperature stability and lower losses are required.
