Aluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor.
Electrolytic capacitors are available in several types as aluminum, tantalum, and niobium versions (Ho et al., 2010). The internal structure of an aluminum electrolytic capacitor consists of two aluminum foils, which are separated by a porous material such as paper which is impregnated with an electrolyte as shown in Fig. 6.11.
Aluminium Electrolytic Capacitors: These are the most common type of aluminium capacitors. They use an aluminium electrode with a thin oxide layer as the dielectric and a liquid or gel electrolyte.
Smaller or low voltage aluminum electrolytic capacitors may be connected in parallel without any safety correction action. Large sizes capacitors, especially large sizes and high voltage types, should be individually guarded against sudden energy charge of the whole capacitor bank due to a failed specimen.
Aluminum electrolytic capacitor construction delivers colossal capacitance because etching the foils can increase surface area more than 100 times and the aluminum-oxide dielectric is less than a micrometer thick. Thus the resulting capacitor has very large plate area and the plates are intensely close together.
