Due to its large capacity and long-term stability, the EEV-FC1C221P is also used in the power supply and stabilization systems of LED lighting, automotive electronics, and other related applications.

Working Principle

An aluminum electrolytic capacitor consists of two metal plates that are separated by a thin dielectric layer of insulating oxide. One plate is made of pure aluminum and serves as the anode. The other plate is connected to the cathode and is usually composed of either pure aluminum or aluminum-doped with other metals. The two plates are then immersed in an electrolyte solution. When a voltage is applied across the two plates, the ions in the electrolyte solution are attracted to the anode, causing the insulating oxide layer to be broken down and electrons to be released from the anode into the electrolyte solution. This forms a conducting path between the anode and the electrolyte solution, which allows current to flow. The size and composition of the anode and cathode electrodes determines the amount of charge that can be stored, and the type of dielectric layer determines the capacitance of the capacitor.

Conclusion

The EEV-FC1C221P aluminum electrolytic capacitor is a component with high rated voltage, large capacity, and long-term stability. It is widely used in a variety of different electrical and electronic devices, and its working principle is based on the attraction of ions to the anode and the creation of a conducting path between the anode and the electrolyte solution. With its reliable performance, it has become an indispensable component in many applications.
