Aluminum electrolytic capacitors are widely used in the fields of consumer electronics, automotive electronics, industrial equipment, military electronics, etc., and are called "chronic diseases" in power electronics components. The B41694A5477Q7 aluminum electrolytic capacitor is a representative of aluminum electrolytic capacitors. This article will explain the application field and working principle of this product.Comparing with other types of capacitors, aluminum electrolytic capacitors have the characteristics of small volume, large capacity, light weight, and low price. Therefore, among all types of capacitors, it is widely used. The B41694A5477Q7 aluminum electrolytic capacitor has a nominal capacitance of 10uF, a rated voltage of 6.3VDC, and a rated interference current of 0.33mA. While having these parameters, it also has a low internal resistance, so that it can be on faster and charge faster, which makes it suitable for power factor correction, UPS bypass and other fields of application.In addition, the B41694A5477Q7 aluminum electrolytic capacitor also has a long life due to its self-healing characteristics, which is suitable for circuits requiring long life, such as automotive electronics, industrial control, and other occasions.The working principle of aluminum electrolytic capacitor is basically the same as that of other types of capacitors. It is composed of two metal electrodes with a dielectric insulator between them. The figure below shows the structure of an aluminum electrolytic capacitor. The two metal electrodes are separated by an electrolyte solution, and the electrolyte solution is called the dielectric. The cathode electrode is an aluminum foil coated with an oxide film that acts as a dielectric.The positive electrode of the B41694A5477Q7 aluminum electrolytic capacitor is the aluminum foil with the oxide film, and the negative electrode is a piece of aluminum foil. The capacitance of the capacitor is determined by the thickness and surface area of the aluminum foil with the oxide film. When a potential difference is applied between the two metal electrodes, the electrons in the electrolyte solution are attracted to the cathode, thus forming a capacitor. When power is removed, the oxide film acts as a dielectric, blocking the current between the two plates, allowing only a small current to flow for a short period of time, allowing the capacitor to self-heal.In conclusion, the B41694A5477Q7 aluminum electrolytic capacitor has small size, large capacity, light weight and low internal resistance, which makes it ideal for power factor correction, UPS bypass, automotive electronics, industrial control and other applications. Its long life and self-healing characteristics make it suitable for long-term applications. In addition, its working principle is the same as that of other capacitors. The aluminum foil with the oxide film acts as the dielectric, and the electrons are attracted to the cathode when a potential difference is applied between the two metal electrodes.
