Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are very widely used, especially in a variety of electronic equipment. Of course, there are also many types of capacitors, so when it comes to B43512A6158M000, what kind of capacitor is it? What is the application field and working principle?

1. Application Field

B43512A6158M000 belongs to aluminum electrolytic capacitors. It is mainly used in the field of telecommunications, graphic audio, mobile phone communications, and other fields of communication. At the same time, because of its superior performance and excellent quality, its application is not limited to these fields and can also be used in various related electronic component fields.

2. Working principle

We can understand from the literal level that aluminum electrolytic capacitor is a type of capacitor with electrolyte. The basic working principle of this capacitor is the physical adsorption effect between two plates separated by an electrolyte. Its structure consists of an anode, a cathode, and an electrolyte. The working principle can be explained by the following steps:

Step 1. When a voltage is applied to the aluminum electrolytic capacitor, an electric field will be generated between the two plates. Step 2. This electric field will cause the positive and negative ions in the electrolyte to be attracted to the two plates respectively, forming electrodeposition on the surface of each plate.Step 3. As the electrodeposited layer increases, the distance between the two electrodes also gradually increases, which increases the dielectric constant and capacitance increases. Step 4. When the charging current is removed, the positive and negative ions that were adsorbed on the surface of the two electrodes are also discharged, and the surface of the two electrodes is restored to its original state, and the capacitance returns to its original value.

3. Advantages and Disadvantages

The working principle of the aluminum electrolytic capacitor is simple and its capacitance is large, which makes it very suitable for large current and high power consumption situations. However, the bandwidth of this capacitor is not suitable for high-frequency circuits, and its self-healing electrochemical properties will make its internal equivalent short-circuit resistance It is reduced, so it will also cause heat. In addition, aluminum electrolytic capacitors will also be damaged due to large polarization intensity, so care must be taken.

In summary, B43512A6158M000 is an aluminum electrolytic capacitor, mainly used in the field of telecommunications, graphic audio, mobile phone communications, etc. Its working principle is simple, the capacitance is large, and it also has some characteristics, such as easy to be damaged by large polarization intensity. Although it has certain shortcomings, it is still widely used in many fields.
