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.
However, by extending the surface area (S) of the aluminum foil electrode by means of etching, and by electrochemically forming a thinner but highly voltage-withstandable layer of oxide layer dielec-tric, the aluminum electrolytic capacitor can offer a larger CV prod-uct per case size than other types of capacitors.
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.
Equation (1) shows that the capacitance (C) increases as the dielectric constant (ε) and/or its surface area (S) increases and/or the dielectric thickness (d) decreases. 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.
