LAK2G221MELB35

Aluminum electrolytic capacitors are an important type of capacitor consisting of two aluminum foils separated by a dielectric layer, most commonly in the form of a paper lining soaked in electrolyte. The surface of the aluminum foils are oxidized, and the oxide layer acts as the dielectric medium.

LAK2G221MELB35 is an aluminum electrolytic capacitor with capacitance of 2200μF, rated voltage of 35V, and a rated temperature range of -40℃ to +105℃. The package size is 22mm x 16mm x 16mm. Its features include low ESR, long life, low leakage current, and high ripple current. It is widely used in various capacitor applications.

The working principle of the aluminum electrolytic capacitor is based on the principle of electrolytic action. The metal oxide layer acts as an electrode, while the electrolyte is used to produce an electric charge between the two. When an electric field is applied between the two plates of the capacitor, a form of electric current, known as the capacitance current, is produced as electrons flow between the plates. The current reverses its direction as the voltage across the plates reverses. This action is also known as \'self-healing\', as the electric field causes the oxide layer to reduce, which then re-forms as the electric field is released.

The main application field for the LAK2G221MELB35 aluminum electrolytic capacitor is in DC and AC circuits, where it can be used for rectification, filtering, and storage of energy. Its low leakage current makes it suitable for use in medical equipment such as respirators, while its high ripple current capability makes it suitable for motor control and power supply circuits. It is also commonly used in high-voltage and high-current applications such as electric vehicles.

In conclusion, the LAK2G221MELB35 aluminum electrolytic capacitor offers a range of benefits due to its low ESR, long life, low leakage current, and high ripple current. It is effective in a variety of applications, including rectification, filtering, medical equipment, motor control, power supply circuits, and electric vehicles. The working principle of the capacitor is based on the principle of electrolytic action, where an electric field is used to generate the electric current known as the capacitance current.
