1. 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.
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.
