Abstract
A method for producing a monolithic electromagnetic component includes preparing a precursor from a ferrite material during an initial step; preparing elements including at least one coil having coil turns; embedding the elements including at least one coil having the coil turns in the precursor embedded in a mold; co-sintering the elements including at least one coil having the coil turns and the precursor compressed by the mold under a predetermined pressure, the predetermined pressure being generated under a load, wherein a pulsed electric current is generated during the co-sintering; discharging the pulsed electric current through the mold such that a temperature in the mold rises; and obtaining the monolithic electromagnetic component in which the precursor is secured to the elements including at least one coil having the coil turns.
