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. 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.
-
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. 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.
