Abstract (en)
[origin: WO2015028389A1] A method for producing a monolithic electromagnetic component comprising a plurality of elements including a base made from spinel ferrite and at least one planar coil comprising a plurality of windings. The method comprises the following series of steps: - during an initial step (110), obtaining a precursor (32) of the ferrite, - during a preparation step (120), in a mould, embedding the elements of the monolithic electromagnetic component including said at least one coil and other than the ferrite in the precursor (32), and - during a co-sintering step (130), rigidly connecting said precursor (32) to the other elements of the monolithic electromagnetic component including said at least one coil by co-sintering under load by means of a pulsed electric current.
