| 摘要 |
The present invention relates to a composite magnetic path inductor including a magnetic core and a coil. The magnetic core has a ring-shaped first magnetic core and a second magnetic core positioned inside the first magnetic core. Both end surfaces of the second magnetic core are connected to respective connection surfaces at corresponding positions on inner side walls of the first magnetic core. The coil is wound around the second magnetic core. The permeability of the second magnetic core is larger than that of the first magnetic core and is preferably 50 H/m or more. The permeability of the first magnetic core is preferably 40 to 100 H/m. |
