Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most commonly used types of capacitors in electrical and electronic circuits. They are typically used to store energy and provide electrical filtering, decoupling, and bypassing services. Aluminum electrolytic capacitors are based on the principle of electrolytic conductivity, where the capacitance is determined by the surface area of the metal plates, the thickness of the electrolyte, and the area between the two plates.

Working Principle

The working principle of the AFK107M2AP44B-F is based on the physics of electrolytic conduction. This capacitors consists of two metal plates which are charged with different voltages. The plates are separated by an electrolyte, which is a liquid or gel that contains ions that conduct electrical current. When electric current is applied, the ions in the electrolyte start to move, creating an electrical potential between the two plates. This potential is known as the electric double layer, and it will increase until it reaches the rated value of the capacitor. This potential will then remain constant until the capacitor is discharged or recharged.

Conclusion

The AFK107M2AP44B-F is an aluminum electrolytic capacitor with a 105°C maximum operating temperature, a 100VDC voltage rating, and a 4.7μF capacitance. Its versatility and reliable performance makes it suitable for a wide range of applications such as switching power supplies, power amplifiers, DC/DC converters, automotive applications, and consumer electronics. The AFK107M2AP44B-F capacitor works based on the principle of electrolytic conduction, where the capacitance is determined by the surface area of the metal plates, the thickness of the electrolyte, and the area between the two plates.
