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 ceramic capacitors hold a charge?
Ceramic capacitors can store charge, but they have a higher leakage current than electrolytic capacitors, so they are less able to hold a charge.
-
4. Does the voltage of ceramic capacitors matter?
Voltage ratings are critical to ensure safe operation. Using a capacitor below the rated voltage may cause premature failure; using a capacitor above the rated voltage may cause immediate damage.
