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.
There are three families of electrolytic capacitor: aluminium electrolytic capacitors, tantalum electrolytic capacitors, and niobium electrolytic capacitors. The large capacitance of electrolytic capacitors makes them particularly suitable for passing or bypassing low-frequency signals, and for storing large amounts of energy.
A non-solid or solid electrolyte capacitor is one in which the electrolyte is not in a liquid or gel form but is a solid. The non-solid electrolyte in principle acts as the cathode, thus forming the second electrode of the capacitor. Differences between electrolytic and non-electrolytic capacitors include the fact that an electrolytic capacitor is unipolar due to the electrolyte, which is similar to a battery.
This article also covers electrolytic capacitors specifics and references for DCL leakage current, ESR, DF measurements in the last section. The dielectric of electrolytic capacitors consists of oxides of aluminum (Al), tantalum (Ta) or niobium (Nb).
The electrolyte must adhere to the whole surface of the anode and cathode foils to have a higher capacitance. It can also repair defects in the anode oxide film as seen before. The nature of the electrolyte influences the temperature and frequency characteristics response of the capacitor (Fig. 4. 5).
The most commonly used model for electrolytic capacitors is based on Arrhenius' law, which describes the influence of the constraints related to the ambient temperature and the current flowing through the capacitors, and on the Coffin-Manson empirical law for the consideration of the applied voltage.
