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. 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.
