2. Structure of Aluminum Electrolytic Capacitor The aluminum electrolytic capacitor has, as shown in Fig.3 , a roll of anode foil, paper separator, cathode foil and electrode terminals (internal and external terminals) with the electrolyte impregnated, which is sealed in an aluminum can case with a sealing material.
An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
Electrolytic capacitors consist of two main components: the electrolyte material and the electrodes. The electrodes are made of metal substrates with oxide films, while the electrolyte can be either solid or non-solid.
An aluminum electrolytic capacitor comprises a dielectric layer of aluminum oxide (Al 2 O 3 ), the dielectric constant (ε) of which is 8 to 10. This value is not significantly larger than those of other types of capacitors.
In general, an aluminum electrolytic capacitor is asymmetrical in structure and polarized. The other capacitor type known as a bi-polar (non-polar) comprises the anodic aluminum foils for both electrodes. 2. Structure of Aluminum Electrolytic Capacitor
Electrolytic capacitors use a chemical feature of some special metals, previously called "valve metals", which on contact with a particular electrolyte form a very thin insulating oxide layer on their surface by anodic oxidation which can function as a dielectric. There are three different anode metals in use for electrolytic capacitors:
