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 are mica capacitors so expensive?
Mica capacitors are expensive because of their excellent electrical properties (such as very low dissipation factor and stable temperature coefficient) and their high production costs.
-
4. Do ceramic capacitors degrade over time?
The capacitance value of ceramic capacitors may decrease slightly over time and environmental factors, but this is usually a slow process.
