ABSTRACT:
A monolithic inductor (10) comprises an elongated substrate having opposite distal ends (14) and (16), each end having an end cap extending from the opposite ends to support the substrate (12) in spaced relation from a PC board, the end caps being formed with non-mounting areas and a deflection area for preventing the substrate resting on the non-mounting area, a substantially steep side wall (16) on the substrate side of the end cap (14) at the non-mounting area, and an inclined ramp extending up to a top of the end cap on the substrate side substantially opposite the non-mounting area, an electrically conductive soldering band (30) extending partially around each end cap, each soldering band having a gap (34) at the non-mounting area for thereby reducing parasitic conduction in the band (30), and an electrically conductive layer formed on the substrate in a helical path extending between the opposite ends and in electrical contact with the conductive soldering bands (30) at the ramps (120).
