Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are various types of capacitors that use an aluminum oxide layer that acts as the dielectric medium, in place of other materials such as paper, mica, rubber, or polyester. This layer, or electrolyte, is formed on the surface of the aluminum foil plates, and acts as a carrier for electric current. Aluminum electrolytic capacitors are characterized by their long operating life, high capacitance, and high operating voltage. Due to their unique construction, they have some unique properties that set them apart from other capacitor types. One such property is that they have a high ripple current rating, which means they are able to store more current than standard capacitors.

ELXG201VSN 181MP25S is a high performance, low ESR (equivalent series resistance) aluminum electrolytic capacitor. This capacitor type is commonly used for application in LED lighting, power supplies, and industrial applications. It has a voltage rating of 200V and a capacitance range of 100 to 1500 μF. Its high ripple current capability and wide capacitance range make it a suitable choice for a variety of applications.

Working Principle of ELXG201VSN181MP25S

In aluminum electrolytic capacitors, both the anode and the cathode are made of aluminum. The anode is an aluminum sheet that is mechanically pressed and formed into a pouch. The electrolyte, or dielectric layer, consists of an oxide film that coats the anode and aids in electrical insulation. The electrolyte is formed when current is passed through the anode and oxidizes the aluminum. This creates an electro-chemical reaction between the anode and the electrolyte, and creates a uniform layer of oxide on the anode.

The cathode is a wound aluminum foil that is contained in a cylindrical structure with a sealed pocket in the center. The cathode also contains a predetermined amount of solid electrolyte that provides a current path between the two electrodes and provides a high capacitance for the capacitor. The cylindrical housing for the cathode also acts as a pressure vessel, providing environmental protection to the electrolyte.

The principle of operation of the ELXG201VSN181MP25S capacitor is relatively simple. When a voltage is applied, an electric field is formed between the anode and the cathode, which creates an electric current through the electrolyte. This current produces a charge differential between the two electrodes and causes the electrolyte to expand. As a result, more charge is stored on both electrodes, thus increasing the capacitance. As the charge created by the capacitor runs out, the charge dissipates and the capacitor returns to its original state.
