OverviewGeneral characteristicsTypes and stylesElectrical characteristicsAdditional informationMarket segmentsSee alsoExternal links
Capacitors are manufactured in many styles, forms, dimensions, and from a large variety of materials. They all contain at least two electrical conductors, called plates, separated by an insulating layer (dielectric). Capacitors are widely used as parts of electrical circuits in many common electrical devices. Capacitors, together with resistors and inductors, belong to the group of passive components
