1. 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. -
2. Why do ceramic capacitors make noise?
Some types of ceramic capacitors (particularly Class 2 ceramic capacitors) produce micro-vibrations when the voltage changes due to their material properties, which in turn cause faint mechanical noise.
-
3. Do ceramic capacitors degrade over time?
The capacitance value of ceramic capacitors may decrease slightly over time and environmental factors, but this is usually a slow process.
-
4. What is the difference between Class 1 and Class 2 ceramic capacitors?
Class 1: has high accuracy and stable temperature coefficient, suitable for precision circuits.
Class 2: has higher capacitance value, but larger temperature coefficient and tolerance, suitable for general applications.
