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. 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. -
3. Can ceramic capacitors hold a charge?
Ceramic capacitors can store charge, but they have a higher leakage current than electrolytic capacitors, so they are less able to hold a charge.
-
4. Can ceramic capacitors be used in AC?
Ceramic capacitors are well suited for AC circuits because they have good frequency response characteristics and low losses.
