1. General Description of Aluminum Electrolytic Capacitors An aluminum electrolytic capacitor consists of cathode aluminum foil, capacitor paper (electrolytic paper), electrolyte, and an aluminum oxide film, which acts as the dielectric, formed on the anode foil surface.
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.
Aluminum foil for capacitors is treated electrochemically to increase the surface area, which improves capacitance. However, the greater surface area tends to decrease bending strength. UACJ and UACJ Foil collaborate to solve this dilemma.
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.
The equivalent series resistance of aluminum electrolytic capacitors has frequency characteristics; so if the frequency is different from the standard, it is converted to meet the standard frequency. If the frequency coefficient Power loss is proportional to the second power of ripple current.
Although the failure rate or the life estimation is generally used in designing a device, the reliability of an aluminum electrolytic capacitor is generally measured by its life (the expected life, in practical use) rather than failure rate since the failure mode of aluminum electrolytic capacitors is wear-out.
