  • Publication number: 20240170202
    Abstract: To improve a coil component having a structure in which a coil part is embedded in a magnetic member. A coil component includes a coil part embedded in the magnetic members and terminal electrodes each made of a conductive paste. Conductor layers constituting the coil part respectively have coil conductor patterns and electrode patterns exposed from a mounting surface. The terminal electrode has an area provided at a position covering the electrode patterns on the mounting surface and areas provided at positions not covering the electrode patterns on the mounting surface. A part of the area constitutes a protruding part protruding in the x-direction. The terminal electrode thus has the protruding part, thereby making misalignment of mounting position in the z-direction less likely to occur at the time of mounting.

A coil component includes: a coil part having a structure in which interlayer insulating films and spirally wound coil patterns are alternately stacked in the axial direction of the coil component; and magnetic element members embedding therein the coil part. The interlayer insulating film covering, from one end side in the axial direction, one coil pattern positioned at the one end in the axial direction is higher in permeability than the interlayer insulating films. Thus, the one coil pattern positioned at the end portion is covered with the interlayer insulating film having a high permeability, so that it is possible to achieve a high inductance value while reducing the entire thickness.

  • Publication number: 20220375679
    Abstract: To improve magnetic characteristics of a coil component having a structure in which an interlayer insulating film is provided between a spiral coil pattern and a magnetic element body. A coil component 1 includes: an interlayer insulating film 41 covering coil patterns CP1 to CP3 from one side in the axial direction of the coil patterns; a magnetic element body M1 filled in the inner diameter areas of the coil patterns CP1 to CP3; and a magnetic element body M2 covering the coil patterns CP1 to CP3 from the one side in the axial direction through the interlayer insulating film 41. The interlayer insulating film 41 has a protruding part 41A radially protruding to the inner diameter area, and the protruding part 41A is curved to the other side in the axial direction. Since the protruding part 41A is curved in the axial direction, the entrance of a magnetic path passing through the inner diameter area is made wider than when the protruding part 41A linearly protrudes to the inner diameter area.
