A capacitor includes a planar electrode layer which is mounted between a pair of dielectric layers. The electrode layer generally is centered inwardly with respect to the dielectric layers leaving an outward margin of dielectric material. One of the dielectric layers has two spaced apart contact members, each having a different polarity from the other. The electrode layer is isolated from electrical contact with any conductor and is buried within the dielectric layers. The electrode layer, in combination with the dielectric layer on which the contact members are mounted and the contact members, allow development of a selected value of capacitance between the contact members. Providing trimmed contact members as well as controlling their size and spacing allow for convenient preselection of desired operative characteristics of the capacitor. The contact members could be positioned on a substrate to which a buried electrode is mounted. |
