LAK2D821MELB45

Aluminum electrolytic capacitors are electronic components that store electrical energy in an electrical field. They are mostly used in the power supply circuits of electronic equipment and are used as conductors between different elements. In terms of capacitor types, the LAK2D821MELB45 belongs to the category of aluminum electrolytic capacitors.

The LAK2D821MELB45 capacitor has an octagon shape and comes with two snap-on terminals for mounting. It has a rated capacitance of 821uF, and a rated voltage of 35VDC. It is rated for a maximum reverse voltage of 6V, and has a ripple current rating of two Amps. The operating temperature ranges between -55 degrees Celsius to +85 degrees Celsius. The capacitor also has a rated lifetime of 5,000 hours.

The working principle of aluminum electrolytic capacitors is based on the Faraday law of electrolysis. In this capacitors, two closely spaced aluminum foils are separated by an insulating material called a dielectric layer, which includes a chemical electrolyte. The positive foil is coated with an oxidized layer, while the negative foil is coated with a layer of aluminum oxide. The charge is stored between these two layers. When an electric field is applied to the capacitor, charges start to accumulate on the two sides of the capacitor. This results in the formation of an electrical field that will store the electrical energy and create an electrical charge on the two foils.

In terms of application, the LAK2D821MELB45 aluminum electrolytic capacitor is used mainly in the power supply systems of various electronic devices. Its low cost, good stability, ruggedness and low leakage make it a popular choice for use in filtering, power supply, and voltage regulation units.
