It is also used in applications where saving space is a concerned and in power supplies and filtering.

Working principle

Aluminum electrolytic capacitors are electrochemical capacitors and are made up of three major components: aluminum foil, an electrolyte and a paper separator. The aluminum foil forms the cathode and the paper separator is the dielectric. The capacitance is determined by the area of the aluminum foil and the thickness of the paper. When a voltage is applied to an electrolytic capacitor, the electrolyte reacts with the aluminum foil plates, which helps form a thin insulating layer of oxide on the aluminum surface. This layer provides an electrical insulation which is a dielectric material that increases the capacitance of the capacitor.When a current is applied, electrons flow from the negative to positive terminal, which causes the oxide layer to be formed. This is called polarization and it increases the capacitance of the capacitor. When a voltage is applied to the capacitor, the electrons will flow from the positive to the negative terminal, discharging the capacitor. When the voltage is removed, the charged electrical field in the capacitor causes electrons to flow back to the positive terminal. This results in the oxide layer to form again on the aluminum plates. This action is what allows the capacitor to behave like a rechargeable battery which allows it to be used for energy storage in many electronic circuits.

Conclusion

The 228LMU050M2CC is a high-performance aluminum electrolytic capacitor used in a wide range of applications.
