It is important to purchase the correct monolithic capacitor

Monolithic capacitors are another name for multilayer ceramic capacitors, referred to as MLCC, and are widely used in electronic instruments. Various small electronic devices are used for resonance, coupling, filtering, and bypassing. The monolithic capacitor is used at the output of the optocoupler. Why is it easy to burn out? What is the reason?

The causes of damage to the monolithic capacitor are as follows:

1. Low pressure resistance.

2. Buy fake and shoddy capacitors.

3. Production welding quality problems.

4. This capacitor is mounted on the edge of the PCB and has mechanical stress and is damaged by cracking.

5. The optocoupler is farther away from the other board or the distance, and the two lines on the optocoupler output induce relatively strong interference.

You can start from the above five points to check whether the pressure resistance of your monolithic capacitor is low, whether the quality is passed, and various reasons may cause problems. Therefore, it is very important to operate and purchase on a daily basis to avoid unnecessary problems.
