The working principle of aluminum electrolytic capacitors is based on their own physical and chemical properties. The capacitor essentially consists of two pieces of thin aluminum foils with an oxide film layer between them, all of which are immersed in a liquid lye. The oxide layer serves as an electrical insulator and provides a path for current flow between the two foils. The oxide layer also ensures that the electrical charges are polarized in the direction of the positive and negative electrodes in the capacitor. The electrical current passes through the aluminum foils and the liquid lye, which, in turn, creates a separation of electrical charges on the electrodes. This separation of charges creates an electric field between the two electrodes and the liquid lye barlow creates an electrical charge that is stored on the metal surfaces of the capacitor.

In conclusion, B43642A2338M000 aluminum electrolytic capacitors are characterized by a capacitance value of 4.7nF, Voltage of 25Vdc, Temperature range of -30 to +105 ℃ and a tolerance of ±20%. This type of capacitor is suitable for applications such as digital systems, AC-motors, pulse circuits, switching circuits and others. The working principle of aluminum electrolytic capacitor is based on a combination of its physical and chemical properties. The oxide layer provides an insulating layer while the electrical current passes through the aluminum foils and the liquid lye, which creates an electrical charge between the positive and negative electrodes.
