1. How do I know if my ceramic capacitor is bad?
Visual inspection: Check for cracks, bulges, or other physical damage.
Multimeter test: Measure the capacitance value to see if it is close to the nominal value, and check for shorts or opens. -
2. 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.
-
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.
