Aluminum electrolytic capacitors are one of the most commonly used components in electronic circuits, and the 865060140001 application field and working principle of aluminum electrolytic capacitors cover the use of capacitors in almost all electronic circuits. This article will introduce you to the application field and working principle of 865060140001 aluminum electrolytic capacitors in detail.

Application field of aluminum electrolytic capacitor

Aluminum electrolytic capacitors are widely used in various electronic fields. For example, in the field of power electronic equipment, aluminum electrolytic capacitors can be used as filters in power grid circuits and reactance components in power factor correction circuits, which can effectively reduce the voltage ripple, reduce the harmonic distortion, and correct the power factor to improve the power quality of the device. In the field of digital circuits, aluminum electrolytic capacitors can be used as timing components, and can also be used as decoupling components, which can reduce the noise interference generated by the interactions between different digital circuits. In the field of precision instruments, in order to reduce the impact of DC voltage on high-precision instruments, an AC bypass filter composed of an aluminum electrolytic capacitor and an inductance is often used.

In addition to the above fields, aluminum electrolytic capacitors can also be used in radio and TV circuits, communication circuits, automotive circuits and computer circuits. It can be seen that aluminum electrolytic capacitors are widely used in various electronic fields, and their application field is very broad.

Working principle of aluminum electrolytic capacitor

Electrolytic capacitors use the principle of electrolysis in electrochemistry, that is, the electrical energy is converted into chemical energy to generate an electric double layer on the surface of the electrolyte, and the electric double layer formed will have an insulating effect. The electrolytic capacitor is a capacitor which uses the electric double layer formed by the anode and the electrolyte as the dielectric, and the anode is usually made of aluminum foil, so it is called an aluminum electrolytic capacitor. In the aluminum electrolytic capacitor, the electrolyte is usually a conductive solution, generally using a mixture of ethylene glycol and boric acid (ET B), which is applied to the aluminum foil as a thin film. Filling the entire capacitor cavity. The electrolytic solution not only acts as a dielectric, but also as a physical support for maintaining the capacitor structure.

When an external alternating voltage or direct current voltage is applied to the aluminum electrolytic capacitor, the current flowing through it will cause the generation of an electric double layer. The aluminum foil anode of the capacitor is polarised by the electric field, and a positive layer is formed on it. The positive layer is isolated from the charges below the surface of the electrolytic solution, which acts as a barrier between the charges and forms the capacitance. When the polarization condition of the capacitor is destroyed and the voltage between the two electrodes is equal to zero, the Electric Double Layer will also disappear. The only characteristic of electrolytic capacitors that is not common to other capacitors is that they have polarity.

In summary, the 865060140001 application field and working principle of aluminum electrolytic capacitors are introduced. In short, aluminum electrolytic capacitors are widely used in various electronic fields, and their working principle mainly depends on the electric double layer formed by the electric field. Aluminum electrolytic capacitors are most commonly used in fields such as power electronic equipment, digital circuits and precision instruments. In addition, they also have polarity, so they must be connected correctly.
