Introduction

Aluminum electrolytic capacitors are a type of electrolytic capacitor that utilizes the physical properties of an electrolyte and an aluminum foil as an electrode with a dielectric oxide film to store electric charge. It is the most widely used type of capacitor in the world, and is very popular mainly because of its large capacitance values.In this article, we will discuss about the 380LQ181M315H022 application field and working principle of aluminum electrolytic capacitors.

Application Field

Aluminum electrolytic capacitors are used in a wide range of electronic devices, from small consumer electronics to very large industrial applications. Smaller, consumer devices such as cell phones, digital cameras, and home entertainment systems, typically use smaller values of capacitance to enable power to the device. Larger capacitors are also used in these applications to provide a consistent power flow even during spikes in voltage.Industrial applications require more voltage and capacitance, so highly complex capacitors are used. Examples of such applications could include industrial motors and power systems, water pumps, solenoids, and high voltage power supply and stabilization circuits, where high levels of precision and reliability are essential.

Working Principle

The working principle of an aluminum electrolytic capacitor is similar to that of other types of capacitors. It consists of two metal plates separated by an insulating material (dielectric material), usually an oxide film created on the surface of an aluminum foil in the case of aluminum electrolytic capacitors. When voltage is applied across the capacitor, a current will flow through the metal plates. This will cause positive ions to collect on one plate and negative ions to collect on the other plate, creating an electric field between them.The dielectric material separates the metal plates and the electric field created between them. This electric field is proportional to the amount of voltage that is applied to the capacitor. The capacitor’s capacitance is proportional to the amount of electric field and the surface area of the plates.When the electric field builds up to a certain level, a breakdown voltage is reached and the capacitor will fail. To prevent this, an additional dielectric film is used to protect the capacitor from overvoltage. This film is made up of various materials such as paper, oil, ceramic, and various polymers. This gives the capacitor some additional protection against overvoltage.

Conclusion

Aluminum electrolytic capacitors are used in a wide variety of devices for a variety of different applications. It is important to understand the working principle of the capacitor and its limitations in order to ensure safe and efficient operation. By understanding the application field and working principle of aluminum electrolytic capacitors, you can make the best selection for your project.
