Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are solid capacitors with a very large capacitance value. They are constructed from two aluminum foils, separated by a paper spacer and soaked in an electrolyte. The types of aluminum electrolytic capacitors used in electronic circuits are those in which the aluminum foils are rolled into tight cylinders, closed at both ends. Each end is provided with an electrolyte, and electrodes are made of aluminum or tantalum deposits.

381LX221M450K042 application field and working principle

381LX221M450K042 is an aluminum electrolytic capacitor which is suitable for storage and filter applications in medium power power supplies, which is used to reduce voltage ripples. This capacitor uses aluminum foil as the electrodes, and has a voltage rating of up to 450 VDC. It also has a capacitance of 221 MFD, which makes it ideal for energy storage and filtering applications.

The working principle involved in this capacitor is that the electrodes of the capacitor store energy and the electrolyte helps to convert the electrical energy into chemical energy and then into mechanical energy. This mechanical energy is then used to store the charge on the terminals of the capacitor. The general working principle is that a voltage applied across two terminals of the capacitor, causes electrons to migrate from one side to the other, thus causing a buildup of electron charge on each terminal.
