ABSTRACT:
An integrated contact is disposed on the end of a conical coil form. Fine magnet wire is soldered to the integrated contact and wound around the coil form to fabricate a high-frequency inductor for use in high-frequency chokes and other high-frequency devices. In one embodiment, the integrated contact is plated on the tip of a polyiron coil form and less than one turn of wire is wrapped around the plated portion of the polyiron coil form. The integrated contact has reduced contact area, reducing capacitive coupling and improving high-frequency electrical performance.
