複合ラインフィルタ
Document Type and Number:
Japanese Patent JP6873615
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the characteristics of a composite line filter.SOLUTION: A composite line filter comprises a magnetic core 300 and two coils. The magnetic core 300 comprises a middle leg 310 constituting a closed magnetic path part, an outer leg 320, a coupling part 330, and a protrusion 340 constituting a sub-magnetic path part. The protrusion 340 protrudes from the outer leg 320 toward the middle leg 310. A gap (gap width Wg1) is formed between a tip of the protrusion 340 and a facing part 312 of the middle leg 310. A lower limit of a dimension (thickness t1) in a X direction orthogonal to a projection direction of the protrusion 340 is 0.5 mm.SELECTED DRAWING: Figure 7
