6 FAQs about [Capacitor aluminum foil cutting operation]
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 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.
What is the anode of an aluminum electrolytic capacitor?
The anode of an aluminum electrolytic capacitor is an aluminum foil of extreme purity. The effec-tive surface area of this foil is greatly enlarged (by a factor of up to 200) by electrochemical etch-ing in order to achieve the maximum possible capacitance values.
What is a cathode in an Alumi-NUM electrolytic capacitor?
In contrast to other capacitors, the counter electrode (the cathode) of alumi-num electrolytic capacitors is a conductive liquid, the operating electrolyte. A second aluminum foil, the so-called cathode foil, serves as a large-surfaced contact area for passing current to the oper-ating electrolyte.
Why do aluminum electrolytic capacitors have colossal capacitance?
Aluminum electrolytic capacitor construction delivers colossal capacitance because etching the foils can increase surface area more than 100 times and the aluminum-oxide dielectric is less than a micrometer thick. Thus the resulting capacitor has very large plate area and the plates are intensely close together.
Does cathode foil have a capacitance?
The cathode foil has a capacitance (Cc) that uses the oxide layer, which formed by the forming voltage or formed naturally during storage (generally 1V or less), as a dielectric. According to the construction of aluminum electrolytic capacitors, Ca and Cc are connected in a series.
