Aluminum Electrolytic Capacitors
An example is the aluminum electrolytic capacitor which contains two closely spaced spooled strips of aluminum foil for the positive anode and negative cathode. These are separated by a thin spacer material soaked in the wet electrolyte. The thin insulating layer of aluminum oxide formed on the anode between the foil plates acts as the dielectric, creating a high-capacitance device …

The engineer''s guide to aluminum electrolytic capacitors
Aluminum electrolytic capacitors tend to be readily available, and with high voltage values (on the order of 700 V). These polarized capacitors usually have a wide tolerance (± 20%), tend to exhibit large leakage currents (5 to 20 µA per µF), and have low self-resonant frequency f RES < 100 kHz). Aluminum electrolytic capacitors tend to have larger values of …

Technical Note
Aluminum, which is main material in an aluminum electrolytic capacitor, forms an oxide layer (Al2O 3) on its surface when the aluminum is set as anode and charged with electricity in elec-trolyte. The aluminum foil with an oxide layer formed thereon, as shown in Fig. 5, is capable of rectifying electriccurrent in elec-trolyte.
