A capacitor consists of two conductors separated by a non-conductive region. The non-conductive region can either be a vacuum or an electrical insulator material known as a dielectric. Examples of dielectric media are glass, air, paper, plastic, ceramic, and even a semiconductor depletion region chemically identical to the conductors. From Coulomb''s law a charge on one conductor wil…

Everything You Need to Know About Capacitor Polarity
For example, if the capacitor''s positive and negative pin numbers in the schematic are 1 and 2 (or 2 and 1), but the PCB footprint has the pin numbers as 2 and 1 (or 1 and 2), there is no 1-to-1, 2-to-2 pin mapping relationship, leading to a correct schematic but an erroneous PCB.
Electrolytic capacitor
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…
