A planar electronic device includes a dielectric substrate having a recess. A functional electrical component is disposed within the recess of the substrate. A vent opening extends within the substrate such that the vent opening intersects the recess within a thickness of the substrate. The vent opening is open to atmosphere such that the vent opening fluidly connects the recess to the atmosphere.

Planar electronic device having a magnetic component

A planar electronic device includes a planar substrate having a cavity configured to receive a ferrite material body therein. The planar substrate has an upper side and a lower side and conductive vias extending through the substrate. Top conductors are provided on the upper side of the planar substrate and are electrically connected to corresponding conductive vias. Bottom conductors are provided on the lower side of the planar substrate and are electrically connected to corresponding conductive vias. The bottom conductors, top conductors and conductive vias define a primary conductive loop and a secondary conductive loop. An upper cover layer covers the upper side and has a high permittivity. The upper cover layer is positioned relative to the top conductors to increase capacitance between the primary and secondary loops.

Planar electronic device

A multilayer inductor device includes a planar substrate, a ferrite body, and an outer and an inner conductive coil. The substrate includes plural dielectric layers with the ferrite body is disposed in the substrate. The outer and inner conductive coils are helically wrapped around the ferrite body. The outer conductive coil includes first upper conductors, first lower conductors, and first conductive vias vertically extending through the substrate and conductively coupled with the first upper and lower conductors. The inner conductive coil includes second upper conductors, second lower conductors, and second conductive vias vertically extending through the substrate and conductively coupled with the second upper and lower conductors. The inner conductive coil is disposed between the outer conductive coil and the ferrite body.
