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.

Aluminum foil is an important part of capacitor, which plays an important role in storing charge and transferring current. Proper maintenance can extend the service life of capacitors and improve circuit performance. The following are some suggestions for maintaining capacitor aluminum foil:

1. Avoid overvoltage: Choose the right capacitor, avoid overload voltage, do not exceed the rated voltage of the capacitor. Overvoltage will cause damage and oxidation of aluminum foil inside the capacitor, affecting the performance and life of the capacitor.

2. Avoid overload: Do not use the capacitor for overload or overload working state, so as not to cause overheating and burning of aluminum foil. Select the rated capacity of the capacitor reasonably to ensure the normal operation of the circuit.

3. Avoid high temperature: try to avoid capacitors in high temperature environment, because high temperature will lead to aluminum foil oxidation, leakage current increase. Avoid using capacitors in direct sunlight and pay attention to heat dissipation.

4. Avoid humid environment: humidity will cause the area of aluminum foil to increase, the internal insulation of the capacitor to decrease, and it is easy to produce leakage. Capacitors should be stored in a humid environment and can be kept dry by desiccant or sealed packaging.

5. Avoid frequent switching: Frequent switching operation will cause changes in the internal pressure of the capacitor, increase the stress of the aluminum foil, and be easily damaged. When designing the circuit, it is necessary to arrange the switching frequency reasonably to avoid frequent operation.

6. Regular detection: Regularly detect the working state of the capacitor, including voltage, capacity, leakage current and other parameters. Once an anomaly is found, replace or repair the capacitor in time to avoid further damage to the aluminum foil.

7. Pay attention to installation: When installing capacitors, be careful not to shift or have poor contact with aluminum foil due to vibration or other reasons. Ensuring that the capacitor is stable and in good contact can effectively extend the life of the aluminum foil.

In general, the maintenance of capacitor aluminum foil needs to pay attention to avoid overload, overvoltage, high temperature, humidity and other factors, regularly detect and timely maintain the working state of the capacitor to ensure its normal operation. Rational use and maintenance of capacitors can extend their service life and ensure stable and safe circuit performance. I hope the above suggestions are helpful.
