Abstract
The present invention relates to switched-mode power supply module and discloses a ferrite mosaic and a magnetic core structure for passive substrate for switched-mode power supply module. The ferrite mosaic includes a supporting plate and numbers of ferrite units stuck on the supporting plate, with each ferrite unit being rectangular. Wherein the ferrite mosaic comprises air-gaps defined between the ferrite units and ferrite glue polymer composites cured in air-gaps, and the magnetic core structure is finished after cutting, laminating and assembling said ferrite mosaics.
