When customers design their capacitor working circuit boards, it because of the ambient temperature is too high and they work at critical voltage for a long time, this situation will cause the top of the capacitor to bulge slightly, which will cause the capacitor to explode, resulting in Danger occurs, causing the working circuit to be damaged and stop working.
Reason analysis: Electrolytic capacitors are also called "aluminum electrolytic capacitors" because their internal electrodes are made of aluminum foil. The inside of the electrolytic capacitor is made of aluminum foil, and paper immersed in electrolyte is used as a medium between the positive and negative electrode aluminum foils. The reason why it is called an electrolytic capacitor is because of the presence of electrolyte. Although the electrolyte content in the electrolytic capacitor is very small, as a liquid, it will vaporize when the temperature rises, causing the capacitor itself to expand, causing the capacitor to explode.
Services we provide: In order to prevent the capacitor from "exploding" due to the pressure generated when the electrolyte inside the capacitor vaporizes, we will sandwich isolation paper soaked in electrolyte between the anode and cathode, roll it into a cylinder, and then package it in an aluminum shell. And an explosion-proof valve (explosion-proof indentation) is pressed on the aluminum shell to discharge the reaction gas when it fails. It is usually made at the top of the capacitor. The indented position will reduce the thickness of the shell, so that the internal pressure of the capacitor will When it is too large, the indentation position will be destroyed first, thereby releasing the pressure.
