Electrolytic capacitor: Properties and operation

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…

New electrolytic capacitors with low inductance simplify inverter

The inductance of electrolytic capacitors came into focus when the progress in the area of voltage source inverters with IGBTs towards greater power ratings required more and more minimized inductances of the power stages.

How to Tell the Polarity of an Electrolytic Capacitor

The capacitor will be damaged and may even explode if inserted backward into the circuit. Unless the capacitor is brand new, never touch both of the wire leads with your fingers, as some capacitors store a high voltage, sometimes for months, after a power source has been removed from them.

capacitor

There are also polymer electrolytic capacitors, which use conductive polymer that, in its monomer form, is a liquid, but when exposed to the right catalyst, will polymerize into a solid material. This is just like super glue, which is a liquid monomer that polymerizes solid once it is exposed to moisture (either in/on the surfaces it is applied to, …
