Introduction

Aluminum Electrolytic Capacitors (AECs) are great options for applications that require high power or decoupling functions, and EMVA100ADA221MF80G is one of the most popular aluminum electrolytic capacitors with its small size and high capacitance. This article will focus on the application field and working principle of this capacitor.

Application Field

The EMVA100ADA221MF80G, having the temperature range of -55~105℃ and a long life of 5,000 hours, is excellent for large-scale applications that require high power functions, for instance, voltage stabilizing, smoothing, and transient filtering. It is also applicable for switching power supplies, DC-DC converters and other power supplies. In addition, with its large capacitance of 1~100μF, the EMVA100ADA221MF80G is suitable for situations where low internal resistance is necessary. And its high stability and reliability of the capacitance makes it an ideal choice for high frequency circuits, such as audio amplifiers, communication equipments and digital/analog integrated circuits. Therefore, it is also popular in the field of information technology and consumer electronics.

Working Principle

The EMVA100ADA221MF80G works on the principle of electrolysis reaction that takes place between the electrolyte and two different metals inside the capacitor. There are two metal plates in the capacitor, one is made of aluminum and other is made of a metal such as nickel, cd, or titanium. These two metal plates are separated by an electrolyte solution, which acts as the dielectric between them.When the capacitor is powered, the battery supplies an electric current, and the charge present on the plates induces an electrochemical reaction in the electrolyte. This reaction produces ions and electrons, which travel between the two electrodes. The current flow on the metal plates and electrolyte creates a capacitance, with the electric field across the electrolyte and the electric charges stored on the plates.The electrolyte of the EMVA100ADA221MF80G is made of a mixture of the polar solvent and electrolyte salts, typically packed in hardening resin or wetting cement. This mixture creates a seal that not only protects the electrolyte from external forces, but also ensures good electrical contact and excellent stability of the electrical characteristics. Also, an effective sealing of the electrolyte helps prevent water vapor from entering the capacitor, allowing it to work at different temperature ranges.

Conclusion

In conclusion, the EMVA100ADA221MF80G aluminum electrolytic capacitor is widely used for its advantages in power applications and stability in circuit design. Its wide temperature range, long life and its large capacitance help the capacitor to perform in the most demanding power supplies, SMPS and audio amplifiers. As the application field and working principle of the EMVA100ADA221MF80G is explained in this article, it is now up to the user to decide if it is suitable for their application.
