Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, commonly known as electrolytic capacitors, are widely used in various types of electronic technology. They are essentially composed of two metallic foil electrodes, aluminum can, and a liquid electrolytic medium filled between them, and because of the wide variety of electrolytic medium, the construction structure of different capacitors is also different. The UVY2G470MHD1TN aluminum electrolytic capacitor is a widely used electrolytic capacitor. This paper mainly discusses its application fields and working principles.

Application Field

The UVY2G470MHD1TN aluminum electrolytic capacitor is mainly composed of a shell, an anode, a cathode, and a polarized liquid electrolyte. It has good electrical performance and is suitable for a wide range of applications. The main features are:

• It has a rated voltage range of 25V to 450V, and a capacitance range of 0.1μF to 100μF.
• Small size and large capacity, because it is impossible to create a large single-layer capacitor, multiple layer capacitors are often used to increase the capacitance.
• It has a high temperature coefficient and is suitable for high temperature applications.
• It has an excellent frequency response, allowing it to be used in a variety of electronic equipment.
• Its dielectric loss is small and its insulation resistance is high.

Therefore, the UVY2G470MHD1TN aluminum electrolytic capacitor is often used in a wide range of electronic equipment, such as electronic musical instruments, electric toys, electronic scales, communication-related equipment, and other low-level audio circuits.

Working Principle

The UVY2G470MHD1TN aluminum electrolytic capacitor works according to the same principle as all other capacitors. When two metal plates are connected together and covered with an insulator to form a capacitor, electric charge can be stored on them. When a voltage is applied to the capacitor, an electric field forms across the insulator, and a current will flow between the two plates when the voltage is large enough. This is called capacitance.

The UVY2G470MHD1TN aluminum electrolytic capacitor is mainly composed of an anode, a cathode and a liquid electrolyte. The anode and cathode are usually made of aluminum foil. An oxide film is formed on the surface of the aluminum foil, which will separate electric charge. The electrolyte will absorb it positively charged ions in electric field and attach to the anode, forming a capacitance layer.

When the voltage is applied, the oxide film of the capacitor will begin to accumulate electric charge, forming an electric field between the capacitor plates, causing an initial current to flow. This current will gradually increase until it reaches a balance, when it will stop. This current is called the capacitance limit current, and it can be used to measure the capacitance of the aluminum electrolytic capacitor. When the capacitor is discharged, the electric charge will be released and the capacitance reduced.

In summary, the UVY2G470MHD1TN aluminum electrolytic capacitor is a type of capacitor with a wide range of applications, and its working principle is based on the ability of a capacitor to store and release electric charge. Its high temperature coefficient and excellent frequency response make it suitable for a variety of electronic equipment.
