There are many studies on the failure modes of electrolytic capacitors, and mainly aluminum electrolytic capacitors. Indeed, from the understanding of the mechanisms and failure modes of a capacitor, it is possible to apply a maintenance in order to know the remaining lifetime of the component.
A typical electrolytic capacitor consists of an outer aluminum shell and an inner aluminum electrode. As shown in Figure 6.17, the electrode is wrapped in gauze permeated with a solution of phosphate, borax, or carbonate. This solution is called the electrolyte.
Their characteristics change strongly with frequency, temperature and aging time. Electrolytic capacitors are among the components whose lifetime has the greatest influence on the reliability of electrical systems. Over the past three decades, many efforts in academic research have been devoted to improving reliability capacitor.
This type of capacitor has an operating temperature of up to 150 °C in some cases, allowing a wide range of operating temperatures. Moreover, compared to other electrolytic capacitors, they are less expensive not only because of the materials used but also because of the manufacturing process. They offer good stability and a long service life.
It is a new method which predicts the life of an electrolytic capacitor by estimating the ESR and the ripple current flowing through the capacitor using temperature and current as a constraint. A life model employing core temperature estimation derived from ESR deterioration and operating conditions is shown.

However, they do not have a lifetime specification in the non-solid AEC sense. failure modes. In order to ensure long life and high reliability of the electrolytic capacitor, some

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 …
