Aluminum Electrolytic Capacitors

The EMZE250ADA220ME73G is part of a broad category of products referred to as aluminum electrolytic capacitors. These capacitors are in wide use because of their compact size, relatively high capacity and good stability under varying temperatures and voltages.

General Description

Aluminum electrolytic capacitors are electrolytic capacitors that use an electrolyte – a liquid or gel containing positive ions – to increase the capacitance of a two sided metallic construction. This type of construction allows for a very compact capacitor with high capacitance for its size compared to other types of capacitors. The main characteristic of this type of capacitor is that it has a relatively high electrical resistance to direct current, and the capacitance can go down somewhat when the current increases. However, aluminum electrolytic capacitors can withstand relatively moderate shocks and overall are designed for long service life and higher temperatures.

Types of Aluminum Electrolytic Capacitors

There are two main types of aluminum electrolytic capacitors: snap-in electrolytic capacitors and screw-terminal electrolytic capacitors. The EMZE250ADA220ME73G product is a snap-in type, meaning it can be easily mounted in a printed circuit board. Screw-terminal types are slightly larger in size and are attached by connecting a screw fitting to a printed circuit board. Each type has a different construction and different characteristics for specific applications.

Application Fields

Aluminum electrolytic capacitors are a popular choice for applications that require electrical energy storage and smooth voltage such as power supplies, DC-DC converters, switching frequency control, AC lines and some audio and communication devices such as radios, amplifiers and computers. Due to their rapid response in switching applications, they’re commonly used in smartphones, telecom systems and more.

Working Principle

The working principle of aluminum electrolytic capacitors is based on an electrochemical reaction that encourages the formation of electrons on one side of the capacitor and a depletion of electrons on the other side. This causes a current to flow between the two sections; as this current flows, it produces an electric field forcing the electrons from one side to the other. This electric energy is stored as potential energy in the capacitance formed between the two sections.

When a voltage is applied to the capacitor, the electrons stored in the capacitance will try to move to the positive plate. This movement of the electrons creates an electric current, which opposes the flow of current and stops it as the electrons reach the positive plate. The excess electric energy is then stored as potential energy in the capacitor, resulting in a charge.

Conclusion

The EMZE250ADA220ME73G is an aluminum electrolytic capacitor, meaning it has aero-soluble cathodes which are less efficient than other types of capacitors. It is used in a variety of applications due to its relatively high capacity and stable operation under varying temperatures and voltages. The capacitor works by using an electrochemical reaction to form electrons on one side and depleting electrons on the other side which produces an electric field between the two, allowing for the storage of electric energy. This capacitor is an ideal choice for a wide range of different applications.
