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. 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. 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. Can ceramic capacitors be used for audio?
Ceramic capacitors can be used in audio circuits, but care needs to be taken to select the right type to avoid introducing unnecessary noise or distortion.
