1. 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.
2. 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.
3. What is the difference between Class 1 and Class 2 ceramic capacitors?

Class 1: has high accuracy and stable temperature coefficient, suitable for precision circuits.
Class 2: has higher capacitance value, but larger temperature coefficient and tolerance, suitable for general applications.
4. Which side of a ceramic capacitor is the positive side?

Ceramic capacitors are non-polarized, so there is no positive or negative side.
