Simplified Low-Profile Cost-Reduced Toroid Assembly

      Disclosed is a low-profile inductor for automated assembly to a
surface mount printed circuit card, utilizing a continuous wire to
form both the toroid windings and the terminal leads.

      Key features of the design include vacuum pickup surfaces (V),
wire guide channels (C), terminating posts (P), and wedge-shaped
standoffs (S).

      Lower cost and improved reliability is achieved with this
design, since an unbroken wire forms the inductor and is then tinned
and wrap-terminated.  No internal soldering or glue is required.
