A Z-directed component for mounting in a mounting hole in a printed circuit board according to one example embodiment includes a body having a top surface, a bottom surface and a side surface. The body has a cross-sectional shape that is insertable into the mounting hole in the printed circuit board. A first portion of the body is composed of a first dielectric material having a first dielectric constant and a second portion of the body is composed of a second dielectric material having a second dielectric constant that is higher than the first dielectric constant. A conductive channel extends through a portion of the body forming a signal path.
