6 FAQs about [Capacitor aluminum foil raw materials]

Can aluminum foil be used to etch a capacitor?

In comparison to other dielectric, similar voltage endurance is provided by dielectrics even if thickness ("d" in the above formula) is thin. By etching the surface of aluminum foil, the effective area of the foil can be enlarged 80~100 times for low voltage capacitors and 30~40 times for middle / high voltage capacitors.

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.

Can aluminum capacitors be mounted on a PC board?

Aluminum capacitors must be mounted on the "top side" of the P.C. board and only allow the bottom side of the P.C. board to come in contact with the solder. Soldering condition must be confirmed to be within Nichicon specification. e Avoid having flux adhere to any portion of the capacitor except the terminal.

Are aluminum electrolytic capacitors polarized?

The construction of an aluminum electrolytic capacitor is illustrated in Fig.1-1. Since the oxide film has rectifying properties, the capacitor is polarized. If both the anode and cathode foils have an oxide film, the capacitors would be bipolar (non-polar) type capacitor.

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 series.
