Title:
コイル部品
Document Type and Number:
Japanese Patent JP6992458
Kind Code:
B2
Abstract:
To reduce difference of DC resistance and AC resistance, while reducing inner and outer boundary difference of the conductor portion.SOLUTION: A coil component includes a first coil part 100 including conductor portions A1-A6 arranged, in this order, from the outer peripheral side to the inner peripheral side, and a second coil part 200 including conductor portions B1-B6 arranged, in this order, from the outer peripheral side to the inner peripheral side. Inner peripheral ends of the conductor portions A1-A6 are connected, respectively, to the inner peripheral ends of the conductor portions B3, B2, B1, B6, B5, B4. With such an arrangement, inner and outer boundary difference of the conductor portions is reduced. Furthermore, impact of magnetic field is made uniform furthermore, because interconnection of the conductor portions, locally increasing AC resistance by impact of the magnetic field, is avoided. Since AC resistance is reduced, difference of the DC resistance and the AC resistance can be reduced.SELECTED DRAWING: Figure 6
