Aluminum Electrolytic Capacitors

10TWL47KEFC8X11.5, or aluminum electrolytic capacitors, are components in an electrical circuit, used to store electric energy, increase coupling accuracy, reduce ripple, filter high frequency signals, and more. This article will explore the application field and working principle of 10TWL47KEFC8X11.5.

Application field

Aluminum electrolytic capacitors have a wide range of electrical applications. One of its most common uses is in coupling circuits. They are also commonly used in power supply filtering circuits, decoupling circuits, DC restoration circuits, phase shift circuits, anti-interference circuits, signal removal circuits, and more. In addition, they are often used in the high and low frequency circuits of electronic instruments and meters.

Because of the wide range of uses for aluminum electrolytic capacitors, they are essential components in many circuits. They can be found in radio, TV, electric test and measurement equipment, computers, audio and video systems, automotive, consumer electronics and many other applications.

Working Principle

The aluminum electrolytic capacitor is a type of polarized capacitor. It consists of two aluminum foil electrodes, and two strips of impregnated paper soaked in electrolyte liquid. The two aluminum foils are separated by oxide film formed on the aluminum foils, which acts as an insulator.

The capacitance of the aluminum electrolytic capacitor is determined by its physical size, namely its length, width, and thickness. The larger the size, the greater the capacitance and the greater the ability to store electrical energy. When the capacitor is connected to a DC voltage source, a certain amount of current will flow through it. As the capacitor is charged, the electrons in the negative electrode are attracted to the positive electrode, and the distance between them is gradually increased.

Since the electrodes are separated by an insulating oxide film, the current will be limited and eventually stop. At the same time, electrostatic lines of force will form between the electrodes, creating an electrostatic field. As the electrostatic field increases, a capacitance will form. This will allow it to store electric energy.

When an AC current is applied to the aluminum electrolytic capacitor, the electrons will oscillate between the two electrodes, and electrostatic lines of force will be generated and focus on the capacitor. This phenomenon is called an electric dipole. The electric dipole can effectively suppress the high-frequency current generated by the AC current, that is, it can filter high-frequency signals.

Conclusion

Aluminum electrolytic capacitors are essential components in many electrical systems. 10TWL47KEFC8X11.5 is one of the most common types of aluminum electrolytic capacitors and has a wide range of applications. Its working principle is based on the formation of an electrostatic field between two electrodes separated by an insulating oxide film, which allows it to store electric energy and filter high-frequency signals.
