Aluminum electrolytic capacitors are among the most widely used capacitors ever invented. With a variety of usage fields, from industrial to consumer applications, they play a major role in modern day electronics. The EGXF350ELL152MM15S, in particular, is a fairly special capacitor, as it offers extremely high capacitance in a small form factor. Its application and working principle are discussed further in this article.

Application

The EGXF350ELL152MM15S capacitor is a very small and precise part, measuring only 5.2 mm in diameter and 15.0 mm in height. This makes it ideal for applications in which space constraints are present. Examples include electronic equipment used in automobiles, as well as on-board computers, computers embedded inside larger pieces of equipment and similar applications. It is often used in power electronics, benefiting from its excellent energy storage capacity and relatively low internal impedance.

Furthermore, the EGXF350ELL152MM15S capacitor is also popular in the audio field, where it is used in amplifiers and other sound equipment. Its extremely low series inductance ensures that the capacitor offers excellent transient performance, from which audio equipment greatly benefits.

Construction & Working Principle

Aluminum electrolytic capacitors are constructed with two electrically conductive plates, separated by a dielectric material which acts as the insulating layer between them. The EGXF350ELL152MM15S capacitor uses an aluminumoxide layer as the dielectric material. This is formed in the presence of an electrolyte solution.

The capacitor works by using the anode plate as the positive side, and the cathode plate as the negative. When a voltage is applied across these two plates, the anode plate will start to draw in electrons, which will cause a build-up of positive charge on the anode plate. This will cause a negative charge to be built up on the cathode plate, and a capacitance will result.

The capacitance of the capacitor can be increased or decreased simply by altering the amount of surface area between the two plates, as well as the thickness of the electrolyte layer. This makes aluminum electrolytic capacitors highly versatile and customizable.

Conclusion

The EGXF350ELL152MM15S is an aluminum electrolytic capacitor, designed for applications in which space is at a premium. Furthermore, it has a very high capacitance and low series inductance, making it ideal for power electronics and audio applications. It is constructed in the same way as all aluminum electrolytic capacitors, by using two electrically conductive plates, separated by an electrolyte layer, with the capacitance adjustable by altering the area and thickness of the electrolyte layer.
