Aluminum Electrolytic Capacitors

B41231C4159M000 is an aluminum electrolytic capacitor, which is a form of capacitor that utilizes the chemical properties of an electrolyte and two electrical conductors to produce a large capacitance. This type of capacitor is typically constructed of two aluminum foil electrodes, with a liquid or solid electrolyte, and a separator. The electrolyte in aluminum electrolytic capacitors serves as an ion source for the aluminum foils.

Application Field

Aluminum electrolytic capacitors are widely used in electronic and electrical systems, due to their high energy density and high capacitance-to-weight ratio. Applications include high-current, bridging, filtering, and voltage-stabilizing circuits. They are also used in audio and video equipment, as well as in AC/DC converters and controllers.

Aluminum electrolytic capacitors are especially well suited for power-supply applications, such as in computers and other electronic products. They are also commonly used in power-management and power-control circuits, voltage-regulators, DC-DC converters, and overvoltage protection.

Given their high energy density, aluminum electrolytic capacitors are often the preferred choice for storing and releasing energy in applications where space is at a premium, such as in portable electronic devices. In addition, they are well suited for pulse-type loads, where their high capacitance and low impedance give them excellent performance.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on the Faraday’s Law of electrolysis. This law states that when an electrical current is applied to an electrolyte, ions are attracted to the electrodes and either form a deposit (in the case of a positive current) or are removed (in the case of a negative current). This causes a double-layer of electrons to be created between the two electrodes, and this is what stores the electrical charge in the capacitor.

This double-layer of electrons is what makes aluminum electrolytic capacitors so much more efficient than conventional capacitors. This is because the layers of electrons allow for a larger surface area, which results in a higher capacitance. This higher capacitance allows an aluminum electrolytic capacitor to store much more electrical energy than a conventional capacitor of the same size.

In addition to their higher capacitance, aluminum electrolytic capacitors also have a longer life than conventional capacitors. This is due to the fact that they are sealed and, as a result, their electrolyte does not evaporate. As such, they can withstand a high amount of heat and operating temperatures, making them ideal for applications that require a long life and reliable operation.
