An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
2. Structure of Aluminum Electrolytic Capacitor The aluminum electrolytic capacitor has, as shown in Fig.3 , a roll of anode foil, paper separator, cathode foil and electrode terminals (internal and external terminals) with the electrolyte impregnated, which is sealed in an aluminum can case with a sealing material.
An aluminum electrolytic capacitor comprises a dielectric layer of aluminum oxide (Al 2 O 3 ), the dielectric constant (ε) of which is 8 to 10. This value is not significantly larger than those of other types of capacitors.
Therefore, the capacitance values of electrolytic capacitors are not directly comparable and differ from those of film capacitors or ceramic capacitors, whose capacitance is measured at 1 kHz or higher. Measured with an AC measuring method at 100/120 Hz the capacitance value is the closest value to the electrical charge stored in the e-caps.
The dielectric thickness of electrolytic capacitors is very small, in the range of nanometers per volt. On the other hand, the voltage strengths of these oxide layers are quite high. With this very thin dielectric oxide layer combined with a sufficiently high dielectric strength the electrolytic capacitors can achieve a high volumetric capacitance.
This type of electrolytic capacitor combined with a liquid or gel-like electrolyte of a non-aqueous nature, which is therefore dry in the sense of having a very low water content, became known as the "dry" type of electrolytic capacitor.
Electrolytic capacitor: Properties and operation
Electrolytic capacitors consist of two electrodes (anode and cathode), a film oxide layer acting as a dielectric and an electrolyte. The electrolyte brings the negative potential of the cathode closer to the dielectric via ionic transport in the electrolyte [7] (see Fig. 2).The electrolyte is either a liquid or a polymer containing a high concentration of any type of ion, although …
