Aluminum electrolytic capacitors (also known as aluminum-electrolytic capacitors or aluminum-electrolytic units) form an integral part of modern electrical systems, and are widely used in a variety of key electronic circuits. The TVAN1112, one of the most widely used aluminum electrolytic capacitor types, has gained huge popularity due to its wide range of applications and ease of use. In this article, we shall explore the TVAN1112\'s application field and working principle.

What is a TVAN1112?

The TVAN1112 is an aluminum electrolytic capacitor that was developed by the Japanese company Toyo Denki in the late 1970s. The TVAN1112 is primarily used to provide a compact, low-cost energy storage device for use in power supplies, digital systems, and many other applications. It is a type of polarized capacitor, meaning that it has two electrodes called the anode and the cathode. The anode is typically made of aluminum, while the cathode is made from a paper material that is impregnated with a liquid electrolyte. The cage that encloses the capacitor is made from a highly durable synthetic material.

Application Field

The TVAN1112 is primarily used in applications where a low-cost energy storage device is required. Some of the more common applications for the TVAN1112 include power supplies, digital systems, motor control, and portable electronic devices. The capacitor is also popular in RC (Radio Controlled) helicopter applications, as it can store a significant amount of energy for a relatively low cost. Additionally, the capacitor is used in automotive, aviation, and industrial applications, thanks to its reliable performance and extended life expectancy.

Working Principle

The working principle of an aluminum electrolytic capacitor is fairly simple and straightforward. When an electric current passes through a circuit, it creates an electromotive force (EMF). This force induces a property known as capacitance, which is defined as the ability of an electrical component to store energy. In an aluminum electrolytic capacitor, the aluminum serves as the anode, while the cathode is made up of a paper with a liquid electrolyte impregnated in it. This combination of copper and capacitance serves to store energy and create an alternating current (AC) in a circuit.

When an electric current passes through the capacitor, the EMF induces a movement of electrons in the aluminum oxide film layer. This film functions as a dielectric, which is what allows the capacitor to store energy. The electrons that are induced to move must eventually return to the aluminum oxide layer, and this process is known as the Faraday effect. Once the electrons have returned to their source, the energy that has been stored can then be released back into the circuit.

Conclusion

The TVAN1112 is a type of polarized aluminum electrolytic capacitor that is widely used in a variety of electronic applications. It is capable of storing a significant amount of energy in a relatively compact device, making it an ideal energy storage solution for many applications. Its working principle relies on a combination of capacitance and aluminum oxide films to store energy. With its reliable performance and extended life expectancy, the TVAN1112 is an excellent choice for a wide range of electronic applications.
