What Are Aluminum Electrolytic Capacitors?

Electrolytic capacitors, also known as electrolytic capacitors, are passive components for energy storage. This component is made of an aluminum foil substrate with a special coating. Electrolysis particularly suitable for smoothing chokes, storage of energy, high-frequency decoupling, high power circuit and other areas. The capacitor has a shell and a leaded terminal end, and is formed by winding the anode foil and the cathode foil on the core.

Application Field of B41690A7388Q7

B41690A7388Q7 aluminum electrolytic capacitors are mostly used in low temperature environment device such as water heaters, surveillance cameras, smart home device and others such products. With its wide range of tolerances, it can also be used in a variety of different applications such as audio, automotive, digital video, robotics, and medical equipment.

Working Principle of B41690A7388Q7

Modern aluminum electrolytic capacitors are equipped with oxidized oxide on the surface of aluminum foil, which serves as the dielectric medium. The distance between positive and negative electrodes corresponds to the distance between diffusion layers, and has a certain insulation resistance and low dielectric loss. As a result of charging, an inversely proportioned electric field is generated in the medium between the two electrodes.

The anodic oxidation process of aluminum capacitors is a three-phase process, namely pre-oxidation, reaction oxidation and passivation. Generally, the oxide film has good chemical stability, forming a good seal with the electrolyte, preventing oxygen from entering or escaping, and the screw is tightly sealed, forming a gas-tight structure. Therefore, there is no leakage of electrolyte. In addition, the anodic oxide film can slow down the aging process of electrolyte.

Conclusion

Aluminum electrolytic capacitors are widely used in low temperature device control circuit, audio, automotive, digital video, robotics, medical equipment and other fields. The B41690A7388Q7 is a wide-ranging aluminum electrolytic capacitor that’s used in many different applications. Understanding the application fields and working principles of aluminum electrolytic capacitors makes sure that the circuits will perform correctly.
