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. Can I replace film capacitors with ceramic capacitors?
In many cases, ceramic capacitors can be used to replace film capacitors, especially when smaller size and lower cost are required. However, it is important to note that ceramic capacitors may have different temperature coefficients and self-healing characteristics, which may affect performance in a specific application.

3. Why do ceramic capacitors short?
Overvoltage: Exceeding the rated voltage may cause internal breakdown.
Mechanical damage: External impact or pressure.
Manufacturing defects: Problems with the internal structure. -
4. Should ceramic capacitors have continuity?
A properly functioning ceramic capacitor should show a certain capacitance value between its pins, not completely on or off.
