1. An inductor comprising:
a base having a top surface, a bottom surface, and at least one side surface, said top surface being spaced from said bottom surface, said at least one side surface connecting said top surface to said bottom surface;
a core located on said top surface, said core extending beyond said top surface in a direction away from said bottom surface, and operatively coupled to said base;
at least one coil extending helically about said core, said at least one coil having at least one end extending outwardly from said core; and
at least one lead operatively coupled to said at least one coil and extending outwardly from said base in a coplanar relationship with said bottom surface, wherein said bottom surface defines at least one recess, said at least one lead being located in said recess and extending outwardly from said bottom surface in said coplanar relationship with said bottom surface.
