Aluminum electrolytic capacitors are widely used in all kinds of electronic products due to their advantages of low cost, small size and good performance. The B41789K8597Q001 is one of the most popular models among them. This article will explain the application field and working principle of this model.

The B41789K8597Q001 aluminum electrolytic capacitor has a wide range of application fields. It widely used in all kinds of radio communication and switching power supply circuit. Besides, it is widely seen as a filter in such as DC stabilizing circuit and the audio frequency filtering circuit. Also, it can be found in computer mainframes, digital TV, monitor power supply circuit and other circuits.

In addition, the working principle of aluminum electrolytic capacitor is relevant to the polarized electrolyte inside the capacitor. This kind of capacitor utilizes the irreversible electrochemical oxidation and reduction reaction to form a dynamic double-layer capacitor, which stores electrical energy in the form of electric double layer to provide a capacitance between the two electrodes. The reversible electrochemical reaction is used to reversibly changes the capacity and electric potential of the capacitor.

To be specific, the capacitor is constructed with two electrodes. A porous anode electrode made from aluminum foil is immersed in an electrolytic solution which contains ions that can be reversibly oxidized and reduced. The other electrode is made from a non-porous material, generally made from carbon. When a voltage is applied across the two electrodes, a small current is conducted through the electrolyte, causing an electrochemical reaction. The electrochemical reaction causes positive and negative ions to move to the electrodes. The positive ions are made of aluminum oxide and build up on the surface of the anode. At the same time, the negative ions are made of electrolyte and accumulate on the surface of the cathode.

This electrochemical reaction keeps happening, and the accumulation of positive and negative ions on the electrodes creates a dielectric layer which produces the electric capacity between the two electrodes. This electric capacity is called electrolytic capacitance and it is a direct measure of the efficiency of the capacitor.

In conclusion, B41789K8597Q001 aluminum electrolytic capacitor is a low cost and widely used capacitor in all kinds of electronic products. It is used in radio communication and switching power supply circuit, computer mainframes, digital TV, monitor power supply circuit and other electronic circuits. The working principle of this capacitor is to enhance the charge and release of electric energy by using the electrochemical oxidation and reduction reaction.
