Aluminum electrolytic capacitors are a kind of electrochemical storage capacitors which use the anode of aluminum oxide film as dielectric medium and have a very large capacity. MAL211690084E3 aluminum electrolytic capacitor is one of the most advanced products in this field. Its application and working principle will be discussed in this article.

MAL211690084E3 aluminum electrolytic capacitors feature high temperature stability and high ripple current capability. Because of its mature technology, their designed service life is 2000 hours. It is mainly used in filters, switching power supply, and medical fields. Meanwhile, it can also be used in drives, UPS/EPS, wind power generation, military industry, and solar energy application.

The working principle of MAL211690084E3 aluminum electrolytic capacitors is the same as the principle of other capacitors. When AC voltage is applied to the aluminum electrolytic capacitor, electric charge will flow between the positive and negative poles of the capacitor. When the current flows to the negative pole, electrons will accumulate on the negative plate and the electric potential of the negative side will increase, resulting in the effect of accumulating electric charge. With the increase of the charge accumulation, the electric potential will fall proportionally so that the potential difference between the two poles can maintain a constant value. This is the principle of electrostatic capacitance.

In addition, the internal structure of MAL211690084E3 aluminum electrolytic capacitors is composed of positive and negative plates, spacers, bobbin, and impregnant. The positive terminal of the capacitor is connected to the aluminum foil, which is treated by anodizing. The oxide film formed on its surface functions as the dielectric medium. The negative terminal of the capacitor is connected to a kind of paper material, also known as impregnant, which is soaked with electrolytes. The impregnant can conduct electricity and contain the electrolytes between the two plates. The bobbin is a coil of wire which is placed between the two poles of the capacitor. It functions to hold the plates and electrodes in the correct position and provide an electrical path for the current.

MAL211690084E3 aluminum electrolytic capacitors stand out from many other electrolytic capacitors because of their excellent temperature stability and high ripple current capability. They are mainly used in sectors such as filter, switching power supply, and medical equipment. The stability of their working principle makes them an ideal choice for many electronic applications.
