Aluminum electrolytic capacitors are a type of capacitor that offers a greater capacity than what is available with ceramic capacitors. This makes them an attractive option for many applications, including the 450UFG680MBN40X55. In this article, we’ll explore the application field and working principle of this specific capacitor.

The 450UFG680MBN40X55 is a low-impedance aluminum electrolytic capacitor with a vertical configuration. It is designed to provide reliable performance when used in motors, drives, and start-up circuits. Its low-loss and high-capacity design makes it ideal for these types of operations. It also provides enhanced surge current capability for improved start-up and operational reliability.

The 450UFG680MBN40X55 is composed of two aluminum foil layers separated by a non-conductive layer of moistened paper. One of the aluminum foil layers is coated with an electrolyte, which is a solution containing ions that can migrate to the other foil layer. The electrolyte is usually made of an aqueous solution of ammonium bicarbonate. This process forms a double layer of oxidized aluminum, known as an anode oxide.

The 450UFG680MBN40X55 has a capacitance of 680μF (microfarads). This value determines the amount of charge it is capable of storing. It is rated for a maximum operating voltage of 105V DC and a capacitance tolerance of ±20%. It is also rated for an operating temperature range of -40°C to +85°C.

The working principle of the 450UFG680MBN40X55 is based on Faraday’s Law of Electrolysis. When a voltage is applied across the terminals, positive and negative ions from the electrolyte migrate to the respective anode and cathode foil layers. As they accumulate, they form an insulating barrier called an electric double layer. This in turn stores electrical energy. When the voltage is removed, the ions are released and the energy is discharged.

The 450UFG680MBN40X55 can be used for a variety of applications that require a high amount of capacitance. These include peak load support for motors and drives, power supply smoothing, inverter circuit stabilization, and battery backups. It can also be used for overvoltage protection in communication equipment and automotive electronics.

In conclusion, the 450UFG680MBN40X55 is an aluminum electrolytic capacitor with a low-impedance and high-capacity design. It has a capacitance of 680μF as well as a rated voltage of 105V DC and a capacitance tolerance of ±20%. Its working principle is based on Faraday’s Law of Electrolysis and it can be used for a variety of applications, including peak load support, power supply smoothing, and overvoltage protection.
