Abstract: An inductor includes a first terminal and a second terminal, a first inductor conductor layer and a second inductor conductor layer, a magnetic core layer, and via conductors. The magnetic core layer is disposed between the first and second inductor conductor layers. The via conductors are connected to the first and second inductor conductor layers. The first and second terminals are electrically connected through the via conductors. The magnetic core layer includes a first magnetic substance portion including a first magnetic substance, and a second magnetic substance portion including a second magnetic substance. Magnetic properties of the second magnetic substance are different from magnetic properties of the first magnetic substance.

Abstract: An electronic module includes a substrate or a lead frame including primary conductive patterns and secondary conductive patterns; a magnetic core; a block coil including a resin body that is located on or above the substrate or the lead frame and that extends over the magnetic core, first terminals that define a first terminal group and that are on or embedded in the resin body, and second terminals that define a second terminal group and that on or are embedded in the resin body; an IC; and a capacitor. Two first terminals of the first terminal group are connected to corresponding primary conductive patterns; two second terminals of the second terminal group are connected corresponding secondary conductive patterns; and a first primary conductive pattern is closer to a second primary conductive pattern than any of the secondary conductive patterns.

Abstract: An isolated DC-DC converter includes a non-isolated DC-DC converter as a primary side. The non-isolated DC-DC converter includes a first inductor, a switch controller, and first and second switches. The non-isolated DC-DC converter is configured to receive an input voltage. The non-isolated DC-DC converter also includes a secondary side including a second inductor, a full wave rectifying circuit, and a filter circuit. The second inductor in the secondary side is coupled with the first inductor in the primary side to define a transformer. The secondary side is electrically isolated from the primary side by the transformer and is configured to output a DC voltage based on a voltage induced in the second inductor via the transformer.

Abstract: An inductor component 1a includes a resin layer 3 and an inductor electrode 6. The inductor electrode 6 includes metal pins 7a to 7d that extend in the resin layer 3 with upper end surfaces thereof exposed from the upper surface 3a of the resin layer 3, and upper wiring plates 8a and 8b that are disposed on the upper surface 3a of the resin layer 3 and that connect upper end surfaces of the short metal pins 7a and 7c and upper end surfaces of the long metal pins 7b and 7d to each other. In this case, the inductor electrode 6 is formed of the metal pins 7a to 7d and wiring plates 8a to 8c that each have a specific electrical resistance lower than that of a conductive paste and plating, and the resistance of the entire inductor electrode 6 can be decreased.
