1. What are ceramic capacitors used for?
Ceramic capacitors are widely used in various electronic devices, mainly for:
Coupling and decoupling: used in circuits to isolate DC signals while transmitting AC signals.
Filtering: remove noise from the power supply or smooth the output voltage.
Resonant circuit: such as oscillators in radio frequency (RF) circuits.
Temperature compensation: some types of ceramic capacitors have temperature coefficients that can be used to stabilize circuit performance.
Bypass: provide a low impedance path for high-frequency signals, thereby reducing the impact on other parts. -
2. 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.
-
3. Should ceramic capacitors have continuity?
A properly functioning ceramic capacitor should show a certain capacitance value between its pins, not completely on or off.
-
4. 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.
