Aluminum Electrolytic Capacitors have a wide range of applications and are used for different tasks. E36D351LPN471TA67N is a product type of aluminum electrolytic capacitors. Its application field and working principle are briefly discussed below.

Application Field

E36D351LPN471TA67N aluminium electrolytic capacitors are mainly applied motor drive applications. They are used for the elimination of current peaks and smoothing of current surges. E36D351LPN471TA67N aluminium electrolytic capacitors are also used in computer-controlled systems, instrumentation, medical equipment, and military applications. These capacitors are ideal for motor drive applications because they provide an optimum combination of high capacitance, high ripple current and high surge current capabilities. Furthermore, they have a low ESR (Equivalent Series Resistance).

Working Principle

An E36D351LPN471TA67N aluminium electrolytic capacitor consists of a cylindrical or rectangular aluminum shell that is filled with an electrolytic liquid. Inside the aluminum body, aluminum and paper foil are rolled and pressed. This forms a structure that resembles a jelly roll. Along one side of the jelly roll, the foil is anodic, meaning that it is the positive electrode of the capacitor and the electrolyte is the negative electrode. The gap between the two faces of the electrolytic capacitor is small, and since there is hardly any space for the charge carriers, the capacitance of the device is high.

During normal operation, the voltage across the capacitor is positive, which attracts anions towards the positive electrode. The anions adsorb on the surfaces of the positive electrode and form an electric double layer. Then, cations move towards the negative electrode, where they attach to the surfaces and form another electric double layer. Thus, two electric double layers form at both faces of the electrolytic capacitor, and since they act as dielectrics, the capacitor is able to store electrical energy.

When the capacitor is discharged, the electric field across the electric double layers disappears, and the charge carriers escape from the surfaces. Overall, this process requires less energy, which makes E36D351LPN471TA67N aluminium electrolytic capacitors efficient energy storage devices.
