Working Principle

The 25PX2200MEFCG412.5X20 aluminum electrolytic capacitor works through the principle of electrolysis. It has two electrolytic-coated layers of aluminum foil, separated by a dielectric medium, usually paper or ceramic. When electric voltage is applied across the two foil layers, a reaction occurs between the electrolyte and the metal foil, forming an electric double layer. This electric double layer acts as a barrier that stores energy and prevents the flow of current.

This capacitor is polarized, meaning that current can only flow in one direction. This is important since it prevents the capacitor from being damaged by high voltage. The capacitor is also rated by capacitance, meaning it can hold a specific amount of charge in its double layer. The higher the capacitance, the more charge the capacitor can hold.

Overall, the 25PX2200MEFCG412.5X20 aluminum electrolytic capacitor is a reliable and efficient capacitor with a wide range of application fields. The logic of its working principle is simple and accessible for those who wish to learn about how capacitors operate.
