Aluminum electrolytic capacitors are electronic components used in electronic circuits. They are commonly used in applications such as audio equipment, TVs, amplifiers, and computers. There are two types of aluminum electrolytic capacitors, one is "wet" which is filled with an electrolytic fluid and the other is "dry" which is a more cost-effective version and usually has a lower quality and shorter life span than the wet type.

The UKL2A6R8KED application field and working principle of an aluminum electrolytic capacitor is relatively simple. A cylindrical structure, along with a metal oxide film and a cathode foil made from aluminum is inserted into the capacitor and forms a series of layers. In between the layers, a liquid electrolyte is placed, usually in the form of an organic solvent or a combination of organic and inorganic materials. This liquid acts as a surface-active agent and helps to promote the necessary physical and chemical reactions for the capacitor to function.

The metal oxide, which forms the anode layer, is responsible for electric charge storage. Its properties make it a good electrical insulator so that the electric field generated by it does not cross over to other components in the circuit. The electrical energy, once stored in the anode layer, is then transferred to the cathode foil, which has a higher oxidation potential than the anode. This causes electrons to flow from the anode to the cathode and allows for charge flow to take place.

When the electrical current reaches the capacitor\'s terminals, a current flow takes place and creates an electrostatic field between the anode and the electrolytic fluid. This electrostatic field tends to flow towards the anode and the electrolyte. As the charge is stored in the anode layer, the electric field is forced to dissipate through the electrolyte. This helps to dissipate the electrical energy stored in the capacitor and is where the term "discharge" comes from.

The capacitor is generally connected to an external circuit as part of the circuit\'s power supply. This ensures that the capacitor will be able to receive a continuous and consistent power supply. As the capacitor is under the influence of electric current, the power supply is connected to the capacitor\'s terminals and current is supplied to the stored energy source in the anode layer, thus allowing charge flow to take place. This charge flow then dissipates the electric energy stored in the anode layer and causes the capacitor to discharge.

Once the capacitor has discharged its stored energy, the electrostatic field generated by the anode dissipates and the capacitor charges again with the external power supply. This process is repeated until the capacitor has reached its maximum capacity of charge storage. During this cycle, the charge stored in the capacitor will reduce as the capacitor is discharged and recharged with the external power supply.

Aluminum electrolytic capacitors are widely used in industrial and consumer electronics, power systems, aircraft, and other applications. They are very reliable, efficient, and cost-effective components that can offer stability and provide a consistent power supply to the electronic circuits.
