The basic form of the capacitor is given as two conductive plates, which are separated by an insulating gap. There are multiple ways of manufacturing the insulating and conductive components, with metal foils, metalized polymer films, electrolytes, and more. But, all of these can be made in a flat rectangular form.A few types of capacitors are not cylindrical and tend to be made by the stacking layers that alternate between insulating and conducting material — for example, Multilayer ceramic chip capacitors.
