One can understand that the electrolytic capacitors has a specific capacitance that is significantly greater than all the other capacitors. An electrolytic capacitor is a polarized capacitor whose anode is a positive plate where an oxide layer is formed through electrochemical principles that limit the use of reverse voltage.
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.

Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal. The benefit of large capacitance in electrolytic capacitors comes with several drawbacks as well. Among these drawbacks are large leakage currents, value tolerances, equivalent series resistance and a …
