Abstract:
A multi-part reactive device comprising:a substrate having a first conductive area and a second conductive area disposed thereon; a first conductive element having a first terminal connected to the first conductive area, and a second terminal connected to the second conductive area, wherein a first current loop is formed extending from the first conductive area, through the first terminal, through the first conductive element, through the second terminal, to the second conductive area; a magnetically-effective core member captivated by the first conductive element to the substrate between the first terminal and the second terminal and encircling the current loop wherein the first conductive area, the first conductive element, the magnetically-effective core member, and the second conductive area form a first magnetic circuit; wherein the first conductive element comprises a surface-mountable component; wherein the substrate has a major surface and an opposing major surface, the multi-part reactive device further comprising at least one via connecting the major surface to the opposing major surface, wherein the first conductive area is disposed on the first major surface coinciding with the at least one via and wherein the first terminal is connected to a portion of the first conductive area coinciding with the at least one via.
