Abstract

A capacitive element is manufactured by using the multilayer printed circuit board technology . The body of the element includes a layer of dielectric material interposed between two layers of conductive material arranged on opposite sides of the layer of dielectric material . Each layer of conductive material is in turn covered , on its free side , with an external covering layer . The material for making the layer of dielectric material is chosen among materials having : a dielectric permeability epsilon_r > 1 , a dielectric rigidity k > 100 kV / mm , and a loss figure Df<=0.002 . Furthermore , the dimensions of the layer of dielectric material are greater than the dimensions of the layers of conductive material , so as to limit the edge effects that might cause discharge phenomena and make the capacitive element flexible .
