Abstract:
A multilayered LC composite component comprising:a multilayered body including a plurality of dielectric layers and internal electrodes having capacitor electrodes and an Inductor electrode laminated via the dielectric layers; input/output external electrodes and a ground external electrode disposed on a surface of the multilayered body; a trimming electrode disposed on a surface of the multilayered body such that the trimming electrode is opposed to at least one of the internal electrodes and electrically connected to the ground external electrode; a trimming groove provided in the surface of the multilayered body; an isolated electrode that is isolated from the trimming electrode by the trimming groove; a coating material filled in the trimming groove to adjust to a desired frequency the coating material having a dielectric constant smaller than the dielectric constant of the dielectric layers, and wherein the isolated electrode is surrounded by the trimming electrode via the trimming electrode.
