Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also called electrolytic capacitors, are devices constructed from two metal plates separated by an electrolyte solution that acts as its dielectric. These capacitors are widely used in many electronic devices for their low cost, easy construction and high capacitance values. The MAL205953689E3 is one such aluminum electrolytic capacitor with included features unique to the manufacturer. In this article we will explore this capacitors application field and working principle.

Working Principle

The working principle of aluminum electrolytic capacitors is based on the Passivation phenomenon, a process of forming a protective coating on the surface of a metal to prevent it from corroding or reacting with its environment. Aluminum electrolytic capacitors are constructed using two aluminum foil plates that act as the anode and the cathode. The plates are separated by an electrolyte solution, which functions as the dielectric between the two plates. An electric current is applied to the plates, which cause the electrodes to build up a surface charge, creating a field between them.

The electric field between the plates causes the electrolyte solution to become polarized, forming an electric double layer on the surface of the electrodes. This double layer behaves as a dielectric material and prevents leakage current across the gap, thus providing the capacitor with its required capacitance. The capacitance of the device will depend on the plates size, the material properties of the electrodes and the amount of charge that they can hold.

Unlike many other types of capacitors, aluminum electrolytic capacitors are able to store a large amount of charge and this makes them useful as power supplies in many applications. Additionally, unlike polar capacitors, the capacity of an aluminum electrolytic capacitor is independent of the applied voltage, meaning that they can withstand large fluctuations in voltage without losing their capacitance. This makes them ideal for use in high-voltage systems or in applications that require transient voltage stabilization.

The MAL205953689E3 aluminum electrolytic capacitor is designed for low-cost, reliable energy storage and can offer high capacitance in a variety of applications. Its low cost, high reliability and wide temperature range make it an ideal choice for applications needing a low-priced and reliable device.
