Ferrite cores are commonly attached to a cable/wire for suppressing the electromagnetic noise emission from digital information and communication equipment. In this paper, an equivalent circuit for the load effect produced by a ferrite core attached to a wire above a ground plane is investigated. A practical method for determining the equivalent circuit parameters is presented, and the resultant load effect is calculated. This approach is validated by measuring the scattering transmission parameters for the wire with attachment of a commercially available ferrite core above a ground plane.
