Aluminum electrolytic capacitors are essential components in various electric circuits. This article will discuss the application field and working principles of the aluminum capacitors, such as the UPS1J681MHD.

A. Application

The UPS1J681MHD capacitors are widely used in electric circuits for different applications. It is mainly used to support the operation of different types of motors. Due to their high capacity, these capacitors can be used for applications with high discharge current and low DC resistance. It can handle high voltage, so it is suitable for high voltage applications, such as high voltage power supplies, high-voltage motors and high-voltage surge protectors. Moreover, its long life makes it suitable for long-term applications, such as switching power supply circuits and computer circuits.

B. Working Principle

The working principle of the aluminum electrolytic capacitors is quite simple. It consists of two leads, one positive and one negative, which are connected to a metal can filled with a conductive liquid electrolyte. The metal can is sealed in order to keep the liquid electrolyte inside. Between the two leads, a series of layers of aluminum oxide and activated carbon are placed. These layers act as a dielectric, which is an insulator layer that prevents the current from passing from one lead to the other. As the capacitor is charged, the electric charge builds up between the two layers. This creates an electric field which, when connected to a circuit, can supply a current.

The amount of charge being stored in the capacitor depends on two factors. The first is the capacitance, which is how much charge can be stored by the capacitor. The second is the voltage rating, which is the maximum voltage the capacitor can support. The capacitance of the UPS1J681MHD is 680uF and it has a voltage rating of 20V, making it suitable for many applications.

The UPS1J681MHD aluminum capacitors are versatile components with a wide range of applications and a long life. They are a reliable and cost-efficient alternative for many electronic circuits, and are widely used for motor, high-voltage, switching power supply and computer circuits. Additionally, the simple working principle of the capacitors makes them easy to use and understand.
