Aluminum electrolytic capacitors are widely used as energy storage components. They feature high capacitance, fast charge-discharge rate, low cost, and wide availability. There are many types of aluminum electrolytic capacitors, and the B43504A9476M87 is one of them. This article will discuss the application field of B43504A9476M87 and its working principle.

Application Field

B43504A9476M87 aluminum electrolytic capacitor is an excellent choice for various applications thanks to its outstanding performance. It features high capacitance, low ESR, long life, and low leakage current. Furthermore, it has a wide operating temperature range of -40°C ~ +105°C. Thus, it is ideal for LED lighting system, AC/DC power supplies, automotive electronics, audio system and more.

Working Principle

B43504A9476M87 aluminum electrolytic capacitor, like other aluminum electrolytic capacitors, is composed of two aluminum foils with a layer of anodic oxide film in between. The internal insulation of the capacitor is formed by a very thin oxide film which is formed on the surface of the aluminum anode by means of high temperature anodization. A separator, usually made of paper, is also used to separate the two layers of the aluminum foil, thus preventing the foil from short-circuiting. The anode electrode is connected to the positive end of the capacitor, and the cathode electrode is connected to the negative end of the capacitor.

The aluminum electrolytic capacitor relies on the electrolyte inside the capacitor to enable charge movement. The electrolyte serves as an electrical conductor charged with ions. When a voltage is applied across the capacitor, the positively-charged ions migrate to the negative electrode where they react and deposit on the oxide film. This is know as the charge stage. During the discharge stage, the opposite process occurs and the negatively-charged ions move to the anode where they react and deposit on the oxide film.

These processes are repeated each time a voltage is applied and the capacitor stores energy in the form of an electric charge. The capacitance of the B43504A9476M87 aluminum electrolytic capacitor is regulated by the surface area of the capacitors aluminum foils and the thickness and uniformity of the oxide layer.

Conclusion

In conclusion, B43504A9476M87 aluminum electrolytic capacitor is an excellent choice for many applications thanks to its high capacitance, low ESR, long life, low leakage current and wide operating temperature range. Its working principle is based on the electrolyte inside the capacitor and the electric charge stored on the oxide film. As a result, it is able to store charge efficiently and effectively.
