6 FAQs about [Capacitor aluminum foil processing process]
How does aluminum foil corrode a capacitor?
Step 1: Corrosion of aluminum foil. The manufacturing essentials of aluminum foil. In order to increase the area of war between the aluminum foil and the electrolyte, the appearance of the aluminum foil in the capacitor is not smooth. Instead, the appearance is formed into a rugged and unyielding shape by electrochemical corrosion.
How do aluminum foil capacitors work?
A 0.05~0.11 mm thick anode foil and a 0.02~0.05 mm thick cathode foil are continuously etched electrochemically in a chloride solution with an AC or DC current. This enlarges the effective surface area of the aluminum foils to attain smaller capacitor sizes. The process develops aluminum oxide (Al203) to form a capacitor dielectric.
How many steps are there in aluminum electrolytic capacitor manufacturing process?
There are eleven steps in the manufacturing Aluminum electrolytic capacitor manufacturing process, and each step is critical. Step 1: Corrosion of aluminum foil. The manufacturing essentials of aluminum foil.
How is an aluminum electrolytic capacitor constructed?
As previously mentioned, an aluminum electrolytic capacitor is constructed by using two strips of aluminum foil (anode and cathode) with paper interleaved. This foil and paper are then wound into an element and impregnated with electrolyte. The construction of an aluminum electrolytic capacitor is illustrated in Fig. 1-1.
Why does an aluminum electrolytic capacitor leak a lot?
When an aluminum electrolytic capacitor is stored under no load conditions for a long period of time, its leakage current tends to increase slightly. This is due to a drop in the withstand voltage of the dielectric caused by the reaction of the anode oxide layer with the electrolyte.
What factors affect the life of aluminum electrolytic capacitors?
The factors that most effect the life of aluminum electrolytic capacitors are acceleration according to the ambient temperature (FT), acceleration according to the ripple current (FI) and acceleration according to the applied voltage (FU). The expected life is calculated by multiplying the specified life time on Nichicon catalog, FT, F1, and Fu.
