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. Can I replace film capacitors with ceramic capacitors?
In many cases, ceramic capacitors can be used to replace film capacitors, especially when smaller size and lower cost are required. However, it is important to note that ceramic capacitors may have different temperature coefficients and self-healing characteristics, which may affect performance in a specific application.

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. Does the voltage of ceramic capacitors matter?
Voltage ratings are critical to ensure safe operation. Using a capacitor below the rated voltage may cause premature failure; using a capacitor above the rated voltage may cause immediate damage.
