A multilayer magnetic sheet is described which comprises a plurality of stacked magnetic component layers separated by first electrically insulating layers. Each of the plurality of magnetic component layers comprises a plurality of isolated magnetic sublayers having a magnetic layer thickness of less than one micron. The multilayer magnetic sheet has a magnetic fraction between about 5% and about 80%; a total magnetic thickness of greater than or equal to 5 microns; and a relative composite permeability of greater than about 20.
