The treatment process before the formation of aluminum foil
The aluminum foil must also be pre-treated before it can be anodized to form a dielectric film. One of the purposes of pre-treatment is to make the surface state of the aluminum foil as pure…

Analysis of corrosion factors affecting aluminum electrolytic capacitors
Corrosion is essentially an electrochemical process, and the one that affects aluminum foil corrosion is an intrinsic factor related to the aluminum metal itself, such as the nature, composition, and structure of aluminum; The second…

Precautions for the use of aluminum electrolytic capacitors
If the voltage is applied in the opposite direction, the circuit will be short-circuited and the capacitor will be damaged. In circuits with unknown or uncertain polarity, use bipolar aluminum electrolytic capacitors.
