Aluminum electrolytic capacitors are typically constructed from two, aluminum foils covered with an insulating material such as paper, and a relatively thick layer of an electrolyte which serves as the capacitor\'s dielectric. One of these aluminum foils serves as the capacitor\'s positive ("anode") electrode, while the other foil serves as the capacitor\'s negative ("cathode") electrode. The terminal that is connected to the positive foil is usually labeled as the + terminal, and the terminal that is connected to the negative foil is usually labeled -.

EKMR451VSN181MP40S aluminum electrolytic capacitors are particularly designed for power system applications, including rectification, motor drives, and power supply. It works on the principle of an electric double layer, which forms when a voltage is applied between the two electrodes. This creates a layer of oppositely charged ions which are attracted into the space between the two foil layers and are insulated from each other by the dielectric layer. This is the equivalent circuit of the topology of the capacitor, where Rt represents the series resistance or equivalent series resistance (ESR), C1 and C2 represent the capacitance itself, at the two electrodes.

The capacitance of an aluminum electrolytic capacitor is determined by the two aluminum foils which comprise the capacitor and the type of electrolyte which is used. The capacitance of the capacitor is determined by the amount of surface area present on the aluminum foils, which in turn, is determined by the type of aluminum used and the number of layers which are present. The electrolyte type is also important as it affects the overall capacitance of the capacitor.
