1. Can I replace film capacitors with ceramic capacitors?
In many cases, ceramic capacitors can be used to replace film capacitors, especially when smaller size and lower cost are required. However, it is important to note that ceramic capacitors may have different temperature coefficients and self-healing characteristics, which may affect performance in a specific application.
-
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. 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. Can ceramic capacitors be used for audio?
Ceramic capacitors can be used in audio circuits, but care needs to be taken to select the right type to avoid introducing unnecessary noise or distortion.
