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. 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. Do ceramic capacitors have a shelf life?
Ceramic capacitors themselves do not have a strict shelf life, but after long-term storage, testing is recommended to confirm their performance.
-
4. Which side of a ceramic capacitor is the positive side?
Ceramic capacitors are non-polarized, so there is no positive or negative side.
