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 ceramic capacitors with film capacitors?
Film capacitors can be used to replace ceramic capacitors in some application scenarios, especially when better temperature stability and lower losses are required.
-
3. 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.
-
4. What is the difference between Class 1 and Class 2 ceramic capacitors?
Class 1: has high accuracy and stable temperature coefficient, suitable for precision circuits.
Class 2: has higher capacitance value, but larger temperature coefficient and tolerance, suitable for general applications.
