Introduction to Aluminum Electrolytic Capacitors

An Aluminum Electrolytic Capacitor ((AEC or Electrolytic Capacitor for short)) is an electronic component consisting of an electrolyte-filled tank separated by a separator, an anode made of aluminum foil and a cathode made of aluminum foil. It consists of two aluminium foils with an electrolytic paper between them. One of the foils is the anode and is made of a special material (such as aluminum) while the other foil is the cathode and is coated with a solid electrolyte. The anode foil is an electrical conductor while the cathode foil is an insulator.

LGX2E331MELA25 Application Field and Working Principle

The LGX2E331MELA25 is a small, yet extremely reliable aluminum electrolytic high-voltage capacitor. This particular model is manufactured to provide the capacity of 33µF at rated voltage of 450VAC (1800VAC peak). It is suitable for applications such as power supplies, professional lightning and speaker systems, etc.

In order to understand the working principle of an aluminum electrolytic capacitor, it is necessary to understand the principles of electric field. As an electric field is applied, the electrons of one electrode are attracted to the other electrode and are repelled by the same force. This creates a flow of charge between the two electrodes.

The electrons in the electrolyte create a plate of electric charge which is the capacitor’s capacitance. The electrolyte also serves as an insulator to prevent the two electrodes from coming into contact with each other. As the capacitor is charged, the electrons move to one plate and the holes are left on the other plate. This creates a potential difference between the two plates and causes charge to build up on one plate while the other plate is depleted.

The LGX2E331MELA25 aluminum electrolytic capacitor works by storing the charge on the anode, the aluminum foil layer of the capacitor. When an electric current is applied, the aluminum layer is attracted to the positive electrode and the electrolyte is repelled by the negative electrode. This causes an electrical field to develop in the electrolyte and a current to flow through the capacitor. This current causes the stored charge to move from the anode to the cathode, and the capacitor is discharged.

Conclusion

The LGX2E331MELA25 aluminum electrolytic capacitor is a small and reliable device suitable for applications such as power supplies, professional lightning and speaker systems, etc. It is designed to provide the capacity of 33µF at rated voltage of 450VAC (1800VAC peak). It works by storing the charge on the anode and when current is applied it causes the stored charge to move from the anode to the cathode, resulting in the capacitor being discharged.
