Causes of monolithic ceramic capacitors failure

In recent years, the development of monolithic capacitors is good, and the frequency of use is getting higher and higher. Monolithic ceramic capacitors are used in various small electronic devices for resonance, coupling, filtering, and bypassing. What is the reason for the failure of monolithic ceramic capacitors?

The reasons are as follows:

1. Dielectric breakdown (not self-healing);

2. The material of the medium changes due to factors such as environment and temperature;

3. The internal circuit and terminals are broken or damaged.

In addition to the above reasons, overvoltage can also cause failure. Therefore, the quality of monolithic ceramic capacitors is important. Monolithic ceramic capacitors have good temperature characteristics and good frequency characteristics. Generally, as the frequency rises, the capacitance decreases. Monolithic ceramic capacitors decrease less and the capacitance is more stable.
