Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most widely used capacitors in electronic and electrical products. ESRG350ETC220ME07D is a common aluminum electrolytic capacitor with larger parameters and smaller size, widely used in ICT, military, aerospace and special fields. Next, let’s find out the application field and working principle of ESRG350ETC220ME07D capacitors.

Application Field of ESRG350ETC220ME07D

ESRG350ETC220ME07D aluminum electrolytic capacitors are mainly used for energy storage, filtering, timing and signal coupling, waveform conversion, equivalent circuit control, signal compensation and other applications.ESRG350ETC220ME07D aluminum electrolytic capacitors are widely used for voltage transmission, lubrication, heat preservation, power control and other applications in shift control, artificial intelligence, digital products, communication, automotive, aviation and aerospace industries. They are also used in power supply control, circuit protection, overvoltage protection, anti-saturation voltage regulation, electric drive and many other industrial applications.

Working Principle of ESRG350ETC220ME07D

The working principle of ESRG350ETC220ME07D aluminum electrolytic capacitors is the same as that of other capacitors. The capacitor is composed of two electrodes separated by an insulator. The two electrodes of an ESRG350ETC220ME07D capacitor are made of aluminum foil. On one of them, a layer of non-conductive polymer electrolyte is applied. The other has an oxide film composed of oxides of certain elements such as aluminum on it. This oxide film has a high breakdown voltage and will be broken down after a certain voltage. As the oxide film cannot be regenerated, it should be replaced after being broken down.When the capacitor is charged, a positive charge accumulates on the non-conductive polymer electrolyte. This attracts the negative charges on the aluminum oxide film. Thus, the total charge inside the capacitor becomes positive. The positive charge is kept inside by the barrier created by the oxide layer, which blocks electrons from entering the capacitance. As a result, current cannot flow through the capacitor thus storing the charge. When a voltage change is applied, the charges on the two electrodes are equalized. This means that the capacitance is decreased and so is the energy stored inside the capacitor. After the process is completed, the charge is discharged and the capacitance value is back to its original state. Thus, the capacitor can store and release charges through a voltage change. To sum up, ESRG350ETC220ME07D aluminum electrolytic capacitors are widely used in ICT, military, aerospace and other special fields. Its working principle is that a positive charge accumulates on the non-conductive polymer electrolyte while a negative charge accumulates on the aluminum oxide film. The two charges attract each other and form a barrier, which blocks electrons entering the capacitance and thus, stores charges. When a voltage change is applied, the charges are equalized, thus decreasing the capacitance and releasing the stored energy.
