| 1. An inductive component comprising:
(1) at least one winding; and
(2) a soft magnetic core molded about the at least one winding, the soft magnetic core being made of a ferromagnetic powder
composite, the ferromagnetic powder composite comprising:
a. a ferromagnetic alloy powder, comprising:
(i) amorphous or nanocrystalline alloy particles that are surface-oxidized; and
(ii) a ferromagnetic dielectric powder, and
b. a cured resin resulting from curing a pourable casting resin formulation that has been poured into a mold about the at
least one winding.
