Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electrical component that stores an electric charge. They are composed of two aluminum foil electrodes coated with a protective anodic oxide layer, separators, and aluminum electrolyte. The aluminum capacitors are also very simple in structure and low in cost, and are widely used in various electronic circuits.

The 381LX471M315A042 model is an example of an Aluminum electrolytic capacitor. Specifically, it is a miniature aluminum surface mount capacitor suitable for use in radio and broadband applications. Its capacitance rating is 471uF with a maximum rated voltage of 35V, and it has both polarization and self-healing capabilities. It is also designed to operate in high temperature environments of up to 125° C.

The 381LX471M315A042 aluminum electrolytic capacitor is mainly used for DC (direct current) filtering, decoupling, and signal conditioning. For example, it can be used in power supplies, voltage regulators, radio receivers, and other electronic appliances that need to filter or decouple electrical signals. Its self-healing capability also makes it ideal for power supplies and high power modules, as it can protect connected electronic components from overvoltage or short circuit damage.

The capacitance value of the 381LX471M315A042 capacitor is determined by the geometry of the anode and cathode electrodes, as well as the dielectric material in between them. This dielectric material can be either an oxide or an organic polymer, and the capacitance value of the capacitor can range from several nanofarads (nF) up to several microfarads (uF). When a voltage is applied to the capacitor, electrons build up on the anode and repel electrons from the cathode, thus creating a charge exchange between the two electrodes and building up a voltage across them.

The dielectric layer of the 381LX471M315A042 capacitor provides isolation and prevents the charge exchange from happening too quickly. The signal passing through the capacitor can then be shaped or attenuated by adjusting the capacitance value. This feature is especially useful in AC (alternating current) applications, as it can be used to filter out low frequency signals or attenuate voltage spikes.

The 381LX471M315A042 aluminum electrolytic capacitor is highly reliable and has a long service life, thanks to its protective anodic oxide layer which shields it from oxidation or short circuit damage. Moreover, it has high power density, low impedance, excellent temperature characteristics, and a good heat dissipation capability, making it suitable for a variety of electronics applications.
