Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in the electronics industry as storage components in electronic circuits. They are constructed from an aluminum oxide film of insulating material, serving as the dielectric, sandwiched between two aluminum foils, forming the electrodes. The outer foil forms the positive electrode, while the inner one forms the negative. By applying a potential difference between the two electrodes, an electric field is generated. This electric field impregnates the oxide film and causes an electrical capacity.

The capacity of an aluminum electrolytic capacitor is determined by the area of the electrodes, the spacing between the electrodes, and the thickness of the oxide film. As such, higher capacity capacitors typically require larger dimensions and thicker oxide film layers. This is why aluminum electrolytic capacitors are larger and heavier than other capacitors.

MAL215373479E3 Application Field and Working Principle

MAL215373479E3 is a multi-layer aluminum electrolytic capacitor type and is mainly used for applications of products in audio-video and informatics field. This capacitor is a device to store electrical energy in air-tight aluminum box by using a dielectric of metal oxide film. The component consists of a pair of aluminum foils rolled up in a multiple layer shape, and is then filled with electrolyte, thus forming a long, air-tight type capacitor.

This aluminum electrolytic capacitor utilizes a specially formulated metal oxide film as the dielectric layer. This film is made up of several very thin layers of aluminium oxide, titanium oxide and other metal oxides. It is this metal oxide film which gives this capacitor its high capacitance rating, defining its charging and discharging rates.

Their multi-layer construction makes them suitable for use in very high power systems. Due to their higher capacitance per unit volume, they can store more energy per component than a single sided foil capacitor. This type of capacitor is also well suited to high frequency applications, as its multi-layer construction reduces the time it takes for the charge to travel across all layers.

The MAL215373479E3 aluminum electrolytic capacitor offers a wide range of operating temperatures which make it suitable for a variety of applications. This also ensures reliable and consistent performance over extended periods of time, and it offers stable characteristics despite the varying environmental conditions. Its ultra-low ESR also makes it very suitable for high ripple current applications.
