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. Does the orientation of ceramic capacitors matter?

Ceramic capacitors are non-polar, so the mounting orientation does not affect their function.
3. 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.
4. 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.
