Aluminum - Polymer Capacitors

Aluminum - Polymer capacitors, or “super capacitors”, are a relatively new technology in the field of electrical components. They are designed to bridge the gap between traditional electrolytic and ceramic capacitors, combining the advantages of both types into one new package. The aluminum - polymer capacitor is most commonly used for ultra-high speed switching and for high power applications. This article will discuss the application field & working principle of the 20SEP33M Capacitor.

Application Field

The aluminum - polymer capacitor is a good choice for applications requiring fast charge & discharge times, combined with high capacitance. Some of the most common applications for these capacitors include electronic power systems, UPSs, electric vehicles, audio amplifiers, and various consumer products. It is also used in aerospace and military applications.

Working Principles

The aluminum - polymer capacitor works by utilizing the electrostatic attraction between two metal plates and a dielectric material. The plates are usually made of aluminum, while the dielectric material is often a specially formulated polymer. This combination is able to store a large amount of electric charge, while at the same time having a very high dielectric constant. This high dielectric constant leads to a small size, while highlighting the fact that charge & discharge times are much shorter than with traditional capacitors.
