Aluminum electrolytic capacitors are widely used in electronic devices, owing to their low cost and high capacitance. The B43501A3687M87 is a radial leaded aluminum electrolytic capacitor, with an operating voltage rating of 25 volts and a capacitance of 470μF. It is designed for use in applications where high capacitance and low cost are required.

The construction of aluminum electrolytic capacitors is fairly straightforward. At the core of the capacitor is a combination of aluminum foil and paper. The two materials form the dielectric of the capacitor. Surrounding the core is a liquid electrolyte, usually an aqueous solution of ammonium bicarbonate. This electrolyte serves to dissolve the oxide layers that delay the conduction of electrons through the aluminum foil.

On top of the electrolyte is a sheet of aluminum foil, often referred to as the anode. This anode provides a surface where electrons can travel to and from. The electrons travel from the anode to another aluminum foil, referred to as the cathode. Lastly, an insulating layer made of polypropylene and paper covers the inside of the capacitor. This layer prevents electrical shorts between the anode and cathode.

The capacitance of aluminum electrolytic capacitors can range from 1μF to 100,000μF. This allows them to be used in a variety of applications. Some of the more common applications include bypassing, decoupling, and filtering. Additionally, aluminum electrolytic capacitors are used in power supply circuits, as they are capable of handling higher currents than most other types of capacitors.
