In this article we will discuss the application field and working principle of B43564E2109M7 aluminum electrolytic capacitors.

Application Field

The B43564E2109M7 aluminum electrolytic capacitor comes in a small package with a footprint of 2mm by 1.25mm, which makes it suitable for use in applications with limited space. These capacitors are typically used in automotive electronics, for voltage filtration, smoothing, energy storage and buffering. Additionally, they are commonly used as power supply filters in consumer electronics, PC motherboards, and portable digital products such as digital cameras and laptops. Because of its operating temperature range, the B43564E2109M7 is ideal for outdoor applications.

Working Principle

An aluminum electrolytic capacitor is composed of two electrodes separated by a liquid electrolyte. The positive terminal of the capacitor is an aluminum foil that has been processed into a porous structure and then covered with an oxide layer. The oxide layer acts as the dielectric, allowing the capacitor to store charge. The negative terminal is a metal or carbon layer that is attached to the positive layer and soaked with electrolyte. The electrolyte is a solution of water, ammonium hydroxide, and other chemicals.

When a voltage is applied to the capacitor, the positive and negative electrodes cause a reaction in the electrolyte, drawing positively-charged ions to the negative electrode and negatively-charged ions to the positive electrode. These ions move through the electrolyte and form an electric double layer, creating a charge separation between the two electrodes. This charge separation is what enables the capacitor to store an electric charge.

In addition to its charge storage capabilities, the B43564E2109M7 also features low leakage current. Low leakage current is important because it ensures that the capacitor will not discharge its charge too quickly. This makes it ideal for applications such as voltage regulation and filtering.

Conclusion

The B43564E2109M7 aluminum electrolytic capacitor is a high-quality, low-leakage, and compact component that is well-suited for a variety of applications. It is typically used in automotive electronics, consumer electronics, PC motherboards, and outdoor applications. Its operating temperature range and small package size make it ideal for use in environments with limited space. Its working principle involves the formation of an electric double layer between two electrodes, which enables it to store and release electrical charge.
