Aluminum Electrolytic Capacitors are a type of capacitors constructed by aluminum foil and dielectric oxide layer. B43740A4828M is a product model of radial type aluminum electrolytic capacitors manufactured by EPCOS AG. This type of capacitors is typically applied to reduce voltage specific feature type of electronic equipment and circuits.Working PrinciplesAluminum electrolytic capacitors use a polarized electrolyte, usually in the form of a gel, rather than a solid dielectric, giving them higher capacitance values than solid dielectric counterparts for a given volume and in a smaller size. When an applied voltage biases the capacitor from the negative to the positive direction, a chemical reaction occurs and forms a thin, electrochemically-grown oxide layer on the surface of the aluminum foil anode. Electrons are transferred to the positive direction, thus creating a layer of electrons in the oxide layer and causing a resultant voltage differential between the two on the conductors. This voltage differential is known as the capacitance and is proportional to the capacitance of the electrolytic electrolyte. The electrolyte used in B43740A4828M is a long-life organic electrolyte with a large voltage withstand capability of 4.7V, which makes it an excellent choice for filter, signal communication, and power supply application in digital audio devices.
