Working Principle

The SLPX181M400C3P3 is an aluminum electrolytic capacitor, meaning it relies on a physical principle called electrolysis to store energy. In an electrolytic capacitor, the anode is made of a metal foil which is coated with an electrolyte, while the cathode is of an oxygen-free aluminum foil. When a voltage is applied across the two terminals, positive ions move across the electrolyte and concentrate on the aluminum foil of the cathode, forming a layer of electrical charge.

When voltage is removed, the stored charge on the layer of aluminum is released and the capacitor can start to conduct a current from anode to the cathode. This process is analogous to a regular capacitor in which a charge is stored on two metal plates separated by a dielectric layer, such as plastic or air.

Conclusion

The SLPX181M400C3P3 is an aluminum electrolytic capacitor with a large capacitance and low cost. It is suitable for use in a variety of applications and has a working principle based on the physical process of electrolysis.
