1. 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.
-
2. 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.
-
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. Which side of a ceramic capacitor is the positive side?
Ceramic capacitors are non-polarized, so there is no positive or negative side.
