OverviewElectrolytic capacitors – basicsHistoryApplication basicsTypes and stylesComparison of the polymer familiesElectrical characteristicsReliability and lifetime

Electrolytic capacitors use a chemical feature of some special metals, earlier called "valve metals", that by anodic oxidation form an insulating oxide layer. By applying a positive voltage to the anode (+) material in an electrolytic bath an oxide barrier layer with a thickness corresponding to the applied voltage can be formed. This oxide layer acts as the dielectric in an e-cap. To increase the capacitors capacitance the anode surface is roughened and so the oxide layer surf…
