Block coil

An electronic module comprising:

• a substrate or a lead frame including primary conductive patterns and secondary conductive patterns;
• a magnetic core located on or above of the substrate or the lead frame;
• first and second block coils, each of the first and the second block coils 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 are on or embedded in the resin body;
• and
• an IC located on the substrate or the lead frame;
• and
• a capacitor located on the substrate or the lead frame;
• wherein
• 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.
