OverviewGeneral informationTypes and features of electrolytic capacitorsHistoryElectrical characteristicsOperational characteristicsCauses of explosionAdditional information
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. Because of their very thin dielectric oxide layer and enlarged an
