1. Is ceramic capacitor AC or DC?
Ceramic capacitors can be used in both AC and DC circuits. They have no polarity, so they can be installed at will.
-
2. What is the difference between ceramic capacitors and electrolytic capacitors?
Polarity: Ceramic capacitors are non-polar, while electrolytic capacitors are polar.
Capacity range: Electrolytic capacitors generally offer larger capacitance values.
Stability: Ceramic capacitors are more stable, especially when the temperature changes.
Lifespan: Ceramic capacitors have a longer lifespan because there is no liquid electrolyte to dry out. -
3. 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. -
4. Which side of a ceramic capacitor is the positive side?
Ceramic capacitors are non-polarized, so there is no positive or negative side.
