Abstract:
A feedthrough type three-terminal electronic component comprising:a monolithic structure including a plurality of stacked layers including at least one pair of an internal signal electrode and an internal ground electrode arranged to face each other with a dielectric layer disposed therebetween; a plurality of external signal electrodes arranged to communicate with extension portions of the internal signal electrodes and disposed on both end surfaces of said monolithic structure; and an external ground electrode arranged to communicate with extension portions of the internal ground electrodes and disposed on both side surfaces of said monolithic structure; wherein internal dummy electrodes which do not contribute to generation of electrostatic capacity are disposed in at least one of: (a) a region defined by both side portions of the internal signal electrodes and the external ground electrode provided on both side surfaces of the monolithic structure, viewing the monolithic structure in planar fashion; and (b) a region defined by both side portions of the internal ground electrodes and external signal electrodes provided on both side surfaces of the monolithic structure, viewing the monolithic structure in planar fashion.
