Wound inductive device has soft magnetic core of ferromagnetic powder composite of amorphous or nanocrystalline ferromagnetic alloy powder, ferromagnetic dielectric powder and polymer

摘要

Inductive device with winding(s) has a soft magnetic core of a ferromagnetic powder composite consisting of a ferromagnetic alloy powder (I) of an amorphous or nanocrystalline alloy, a ferromagnetic dielectric powder (II) and a thermoplastic or thermosetting polymer (III). Independent claims are also included for the following: (1) production of the device by preparing a mold, (I), (II) and (III), and either: (i) Filling the mold with (I) and (II), adding (III) and curing (III); or (ii) Mixing (I), (II) and (III), filling the mold with the resultant powder and curing; and (2) the use of ferromagnetic carbonyl metal powders for the production of soft magnetic cores of inductive devices.
