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 be used in AC?
Ceramic capacitors are well suited for AC circuits because they have good frequency response characteristics and low losses.
-
3. Why are mica capacitors so expensive?
Mica capacitors are expensive because of their excellent electrical properties (such as very low dissipation factor and stable temperature coefficient) and their high production costs.
-
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.
