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. 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.
-
4. 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.
