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 short?
Overvoltage: Exceeding the rated voltage may cause internal breakdown.
Mechanical damage: External impact or pressure.
Manufacturing defects: Problems with the internal structure. -
3. 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.
-
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.
