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.

A capacitor is an electronic component widely used in electronic devices that is capable of storing charge and releasing it in a circuit. The aluminum foil of capacitor is one of the important components of capacitor, the performance of aluminum foil will directly affect the performance of the whole capacitor.

First, the thickness of the aluminum foil will affect the voltage resistance of the capacitor. As one of the plates of the capacitor, aluminum foil needs to have a certain thickness to withstand the electric field force and voltage, if the thickness of aluminum foil is insufficient, it is easy to lead to the leakage phenomenon of the capacitor, thus affecting the service life and performance of the equipment.

Secondly, the purity and treatment process of aluminum foil will also affect the performance of capacitors. The higher the purity of the aluminum foil, the better the conductivity, which can reduce the internal resistance of the capacitor and improve the efficiency of the capacitor. At the same time, through the excellent treatment process, the aluminum foil can be better combined with the dielectric to form a more stable capacitor structure, thereby improving the stability and reliability of the capacitor.

In addition, the surface treatment of aluminum foil is also an important factor affecting the performance of capacitors. The oxidation layer, coating or coating on the surface of aluminum foil can improve the oxidation resistance and sealing performance of aluminum foil, effectively prevent aluminum foil from moisture, oxidation or damage, thus extending the service life of capacitors.

In summary, capacitor aluminum foil has an important impact on the overall capacitor performance. The selection of aluminum foil with appropriate thickness, high-quality materials, good treatment process and surface treatment can improve the performance and reliability of capacitors and ensure the normal operation of equipment. Therefore, in the design and production process of capacitors, it is necessary to pay attention to the selection and treatment of aluminum foil, a key component, so as to improve the overall performance of capacitors.
