construction of aluminium foil capacitor

1. General Description of 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. Since the oxide film has rectifying properties, a capacitor has polarity.File Size: 1MBAluminum Electrolytic Capacitors This structure of an aluminum electrolytic capacitor results in a characteristic result because the second aluminum (cathode) foil is also covered with an insulatin oxide layer naturally formed by air. Therefore, the construction of the electrolytic capacitor consists of two single series-connected capacitors with capacitance CAluminum Electrolytic Capacitors cathode) of aluminum 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 pass-ing current to the operating electrolyte.
