Aluminum foil for capacitor

Aluminum foil for capacitor

Combined with the excellent electrical conductivity of aluminum, strong plasticity. Aluminum foil can be stably rolled at a thickness of more than 0.0045um. Very widely used in capacitor industry. Basically divided into: high voltage capacitor, electric heater, electronic capacitor, transformer and so on. We provide capacitor aluminum foil, uniform thickness (±3%), strict width (±0.5mm), flat end face (±0.1mm), all indicators are higher than the national standard (GT/T22642-2008) an order of magnitude. Our advanced packing method is clean, moisture-proof and easy to access. Has been praised by domestic and foreign capacitor enterprises.

Capacitor aluminum foil is an important part of the capacitor, its role is to act as the electrode of the capacitor. A capacitor is an electronic component used to store electrical charge and transfer it in a circuit. The role of aluminum foil in capacitors is mainly reflected in two aspects: to provide the electrode of the capacitor, and to increase the capacity of the capacitor.

First of all, aluminum foil, as the electrode of the capacitor, plays the role of connecting the external circuit and the internal medium of the capacitor. A capacitor is composed of a layer of medium separated between two electrodes, and aluminum foil is one of the electrodes. The aluminum foil transfers the charge of the external circuit into the capacitor by connecting the leads of the capacitor. At the same time, the aluminum foil also allows the charge in the capacitor to flow in the external circuit, thus completing the charge and discharge process of the capacitor. Therefore, the role of the aluminum foil is to connect the capacitor and the external circuit to achieve the transfer of charge.

Secondly, aluminum foil can also increase the capacity of capacitors. In a capacitor, the size of the capacitor depends on the structure of the capacitor and the nature of the medium, but the electrode of the capacitor also has a great influence on the capacity of the capacitor. Aluminum foil is used as the electrode of the capacitor, and its area and shape will affect the capacity of the capacitor. Specifically, the larger the area of aluminum foil, the larger the capacity of the capacitor; The smaller the distance between the aluminum foil and the other electrode, the capacity of the capacitor will also increase. Therefore, by designing a suitable aluminum foil shape and structure, the capacity of the capacitor can be increased, making the performance of the capacitor in the circuit more superior.

In general, the role of aluminum foil in capacitors is irreplaceable. It is the electrode of the capacitor, connects the capacitor and the external circuit, and can increase the capacity of the capacitor and improve the performance of the capacitor. Therefore, in the design of electronic circuits, the choice and design of aluminum foil are very important, which can affect the performance and stability of the entire circuit.
