1. General Description of Aluminum Electrolytic Capacitors An aluminum electrolytic capacitor consists of cathode aluminum foil, capacitor paper (electrolytic paper), electrolyte, and an aluminum oxide film, which acts as the dielectric, formed on the anode foil surface.
There are two main types of electrolytic capacitors: aluminum and tantalum. Aluminum electrolytics have a chemical paste (the electrolyte) filling the space between their foil plates. When voltage is applied, a chemical reaction forms a layer of insulating material on the positive plate.
A 0.05~0.11 mm thick anode foil and a 0.02~0.05 mm thick cathode foil are continuously etched electrochemically in a chloride solution with an AC or DC current. This enlarges the effective surface area of the aluminum foils to attain smaller capacitor sizes. The process develops aluminum oxide (Al203) to form a capacitor dielectric.
The cathode foil has a capacitance (Cc) that uses the oxide layer, which formed by the forming voltage or formed naturally during storage (generally 1V or less), as a dielectric. According to the construction of aluminum electrolytic capacitors, Ca and Cc are connected in a series.
In contrast, a “foil” electrode capacitor uses an electrode material more akin to household aluminum foil, which is thick enough (on the order of micrometers) to be mechanically self-supporting.
