The color of the two poles of the chip capacitor is silver-gray. Some people will find that some chip capacitors have black spots and black spots. What is the reason?
Will the black chip capacitors affect the use?
The YGEO agent will explain to you the reason and effect of the black dots in the two segments of the chip capacitor.

If the chip capacitor appears black, it means that the chip capacitor has been oxidized. The oxidation mentioned here refers to the oxidation of the outermost tin layer of the two terminal electrodes of the chip capacitor and let it oxidize.
There are two reasons:
①Prolonged exposure to high temperature
② Long-term humid air
Will there be any effect after the chip capacitor is oxidized?
Under normal circumstances, the chip capacitors are oxidized and blacked, which will affect the machine and cause poor soldering.
So how should we save the chip capacitors?
1. Keep the chip capacitors in the original packaging bag as much as possible
2. Avoid storing in an environment with water, salt water or oil.
3. Do not store the chip capacitors in a place with high temperature and high humidity, storage place: indoor.
