Aluminium electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminium foil with an etched surface. The aluminum forms a very thin insulating layer of aluminium oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers.

AI Customer ServiceAluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor.
The typical temperature range for aluminum electrolytic capacitors is –40 oC to 85 oC or 105 oC. Capacitance varies about +5% –40% over the range with the capacitance loss all at cold temperatures. Capacitors rated –55 oC generally only have –10% to –20% capacitance loss at –40 oC.
Dielectric of an aluminum electrolytic capacitor is an oxide film formed on surface of aluminum foil by forming process. When voltage is applied to the dielectric, polarization occurs due to dielectric effect. The polarization does not immediately respond to the electrical field and may delay by the elastic viscosity of the molecules.
If both the anode and cathode foils have an oxide film, the capacitors would be bipolar (non-polar) type capacitor. These technical notes refer to "non-solid" aluminum electrolytic construction in which the separator is impregnated with liquid electrolyte. There is another type of aluminum electrolytic capacitor that uses solid electrolyte.
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.
While tolerances of ±5% and ±10% are routine for ceramic capacitors, ±20% and –10% +50% are the norms for aluminum electrolytic. This makes aluminum electrolytics the choice for high-capacitance applications like rectification filters and power hold up where more capacitance is a bonus.
