Planar magnetic device and wiring method

The embodiment of the invention discloses a planar magnetic device and a wiring method, and belongs to the technical field of electronics. The planar magnetic device comprises a side column which is provided with a first air gap; the middle column is parallel to the side columns, and a second air gap is formed in the middle column; and the coil windings are wound on the middle column, the line width of the coil windings close to the first air gap or the second air gap is small, and the line width of the coil windings far away from the first air gap and the second air gap is large. Therefore, the problem of large loss of a planar magnetic device in the related technology can be solved. 本申请实施例公开了一种平面磁性器件及布线方法，属于电子技术领域。其中，该平面磁性器件包括：边柱，边柱上设有第一气隙；中柱，与边柱平行，中柱上设有第二气隙；线圈绕组，缠绕在中柱上，且靠近第一气隙或第二气隙的线圈绕组的线宽小，且远离第一气隙和第二气隙的线圈绕组的线宽大。因此，本申请实施例可以解决相关技术中平面磁性器件损耗大的问题。
