Abstract (en)
[origin: WO9736307A1] A method is provided of producing an LC-circuit in form of a single component, in which the inductor and capacitor elements are arranged atop one another, and where the inductor elements are formed by ferromagnetic zones made of layers (6, 8) of ferrite of a high permeability, and between which electrode layers (7) are provided, and where the capacitor elements are formed by dielectric zones made of layers (9) of dielectric with electrode layers (4, 5) on both sides, said inductor and capacitor elements being produced by way of tape- or thick-film technology. According to the invention, the capacitor elements are initially provided and being subjected to a sintering at a relatively high temperature, whereafter the inductor elements (6, 7, 8) are applied and a sintering is performed at a considerably lower temperature. In this manner undesired reactions are avoided between the two zones.
