Is the capacitor attached to the carbon foil positive?
The above-mentioned positive and negative electrodes are wound around their central axis, and the core of the aluminum electrolytic capacitor is formed. Then, the core is placed in an aluminum shell and the aluminum electrolytic capacitor is formed.
In order to facilitate the manufacture of capacitors, usually the electrolyte solution is immersed in special paper, and then with a place of aluminum and immersion in electrolyte solution with the paper together, so you can more easily in the original aluminum foil to lead the negative.
The negative electrode of the capacitor is made of electrolyte, the electrolyte is generally composed of boric acid, ammonia, ethylene glycol and other components.
Electrolytic capacitors of the positive plate with aluminum foil, immersed in the electrolyte for anodic oxidation treatment, aluminum foil surface will produce a layer of aluminum oxide film, the thickness is generally 0.02 - 0.03μm. This layer of oxide film is positive and negative insulation between the plates.
