Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitors that use a thin aluminum oxide film as a dielectric together with an electrolyte, usually an aqueous solution of potassium hydroxide, that is applied to the capacitor body. They are widely used in consumer electronics, notably in motor controllers, computers, and telecommunications equipment, due to their large energy storage and power density. Aluminum electrolytic capacitors are available in various sizes, shapes, and voltage ratings.

25ZLG680MEFC10X20 application field and working principle

A 25ZLG680MEFC10X20 aluminum electrolytic capacitor is a type of aluminum electrolytic capacitor that is designed for use in a variety of applications, such as power supplies, audio/video, light dimming supplies, and medical devices. It has a capacitance of 680 µF and a rated voltage of 10V. Aluminum electrolytic capacitors like this one have several advantages over other types of capacitors, including their high capacitance, low cost, and long service life.

The 25ZLG680MEFC10X20 capacitor consists of an anode (positive terminal), a cathode (negative terminal), and a dielectric material (aluminum oxide). The anode is made from aluminum metal foil, while the cathode is made from electrolytic foil, such as aluminum or tin. The dielectric is formed by a thin film of aluminum oxide on the foil by a wet chemical process.

The working principle of aluminum electrolytic capacitors is based on an electrochemical reaction between the anode and the electrolyte. When a voltage is applied to the terminals of the capacitor, electrons are attracted to the cathode, causing a current flow between the anode and the cathode. This current flow causes an oxidation-reduction reaction between the anode and the electrolyte, which produces positive charged ions (anions) at the anode and negative charged ions (cations) at the cathode. The positive ions are attracted to the anode, while the negative ions are attracted to the cathode. This sets up an electric field within the capacitor, allowing it to store electrical energy.

Aluminum electrolytic capacitors like the 25ZLG680MEFC10X20 are also relatively easy to install, and are often used in applications such as power supplies, audio/video equipment, light dimming supplies, and medical devices. As they are available in a variety of sizes, shapes, and voltages, they are able to meet any specific application requirements. Furthermore, they offer good performance, and their long service life makes them a cost-effective choice for many applications.
