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.
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.
Until the wound construction of aluminum foil capacitors, this type of capacitor was bulky and heavy. There are different sizes of capacitor ranging from 3 mm in diameter for 5 mm in height up to 90 mm for 210 mm .
For 360 V < U < 500 V, the storage time is 1 years. For U > 500 V, the storage time is 6 months. In this section, the various steps in the construction of an aluminum electrolytic capacitor are described. There are several steps to build an AEC: Etching: The anode foil is made of an almost pure aluminum foil, 40 to 110 μm thick.
The cathode foil has a capacitance (Cc) that uses the oxide film, which formed by the forming voltage or formed naturally during storage (generally it should be 1V or less), as a dielectric. According to the construction of aluminum electrolytic capacitors, Ca and Cc are connected in a series.
