Document Type and Number:
WIPO Patent Application WO/2021/160193
Kind Code:
A3
Abstract:
Disclosed is an SMD transformer and a production method therefor, said SMD transformer comprising a glue layer and a wound portion, the wound portion being disposed within the glue layer and comprising an I-shaped magnetic core and a winding package wound on the core column of same; a lead-out end of the winding package is connected to an electrode, said electrode being exposed on the surface of the glue layer. The glue layer is obtained by compression molding of a magnetic molding compound. Compared to existing SMD transformers having equivalent performance indices, the present SMD transformer is dimensionally smaller by a proportion that can exceed 50%, and no bobbins or insulating tape are required in production. The wound portion in the present SMD transformer is further wholly enclosed within the glue layer, ensuring high product reliability, and support of PSIP packaging environments.
