摘要： A transformer includes a bobbin, terminal electrodes, a core, a primary winding, a secondary winding, and an additional winding. The bobbin is made from an electrically insulating material and has a tubular portion defining an internal space. The tubular portion has an outer peripheral surface providing a first through third sections arrayed side by side in an axial direction of the tubular portion. The terminal electrodes are provided at the bobbin for electrical connection to the windings. The core is inserted into the internal space. The primary winding has an insulating layer and is wound over the first section. The secondary winding has an insulating layer and is wound over the third section. The additional winding is wound over the second section and has an insulation layer whose insulating performance is greater than that of the insulation layer of the primary winding and the secondary winding.

摘要： A ferrite core includes an end face portion, a pair of outer legs protruding from the end face portion, and a center leg protruding from the end face portion between the pair of outer legs. A width W1 close to one end portion of the center leg in a Y-axis direction perpendicular to a facing direction of the outer legs is smaller than a width W2 close to the other end portion. According to this configuration, a circuit component may be positioned close to the end portion. A transformer includes the ferrite core.
