What Aluminum Capacitors Are, And What Should We Attention When We Use Them

Aluminum capacitors are electrical components that use aluminum to conduct electric currents. These components are found in the most complex electronic devices, such as computers and car batteries. This blog article will explore what aluminum capacitors are and why they’re used.

An introduction to an aluminum capacitor

Aluminum electrolytic capacitors are made of an aluminum cylinder as the negative electrode, which is filled with liquid electrolyte and inserted into a bent aluminum strip as the positive electrode. It must also be treated with DC voltage to form an oxide film on the positive plate as a medium.

Precautions when using aluminum capacitors

  1. First, it is necessary to clarify that aluminum electrolytic capacitors will fail. It is only a matter of time. Many reasons affect the life of capacitors, such as overvoltage, reverse voltage, high temperature, rapid charge, discharge, etc. Under normal use, the biggest impact is temperature because the higher the temperature, the faster the volatilization loss of the electrolyte. It should be noted that the temperature here does not refer to the ambient or surface temperature but refers to the working temperature of the aluminum foil.
  2. The actual voltage of the electrolytic capacitor in the circuit cannot exceed its withstand voltage value. In the filter circuit, the withstand voltage value of the capacitor should not be less than 1.42 times the RMS value of the AC. When using electrolytic capacitors, be careful not to reverse the positive and negative poles.

Conclusion

Aluminum capacitors are a common component in electronic equipment, and their purpose is to allow electricity to flow freely through the device. If you’re ever unsure whether or not your electronic device uses an aluminum capacitor, be sure to check the label – most devices will list it there.
