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.
