RCER71H332K0A2H03B vs RCER71H332K0K1H03B

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. Do ceramic capacitors deteriorate over time?

While ceramic capacitors are relatively stable, their capacitance value may decrease slightly over time, especially under extreme environmental conditions. However, this change is usually small and will not significantly affect most applications.
4. 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.
