Working principle

The working principle of UPW1E390MDD6 is based on electric double-layer capacitance. It is constructed with a non-polarized electrolyte immersed in an extremely thin film of aluminum oxide, which acts as the dielectric layer. There is also a separator between the two electrodes of the capacitor which prevents direct charge transport between them. When the two electrodes of the capacitor are supplied with equal and opposite charges, an electric double-layer is formed. An electric double-layer consists of two charged planes separated by an electrolyte, which consists of two oppositely charged species, one cation and one anion. This electric double-layer serves as a dielectric, thus enabling a capacitance. The capacitance of UPW1E390MDD6 is determined by its geometry, the thickness of the dielectric layer, the type of electrolyte used and the ions it contains. It also depends on the area of the electrodes. All of these parameters affect the capacitance of the capacitor.

Conclusion

In conclusion, UPW1E390MDD6 aluminum electrolytic capacitor is a type of electric double-layer capacitor that offers excellent features and performance. It is suitable for many applications, such as power supply systems, aerospace and military applications, automotive and automotive-related industries. The working principle is based on electric double-layer capacitance, and the capacitance is determined by the geometry, thickness of the dielectric layer and the type of electrolyte.
