  • Patent number: 11929201
    Abstract: A surface mount inductor includes a coil including a wound portion and a feeder end portion drawn out from the wound portion, a compact that contains a magnetic powder and that encapsulates the coil, and an external terminal disposed on the compact and connected to the coil. The compact has surfaces including two pressed surfaces, opposing each other in a direction of an axis of the wound portion and formed by being pressed in the direction of the axis, and a non-pressed surface, adjacent to the two surfaces and not pressed. The coil is disposed so that the axis of the wound portion is parallel to a mount surface of the compact. The mount surface is included in the non-pressed surface, the feeder end portion is exposed from the mount surface, and the external terminal is formed on only the non-pressed surface and connected to the feeder end portion.

  • Patent number: 11631528
    Abstract: The inductor includes a coil including a winding portion formed by winding a conductor wire having an insulating coating and lead-out portions extended from the winding portion, and a body made of a magnetic portion including magnetic powder and resin, and containing the coil, and outer electrodes on a body surface. The body includes a mounting surface, an upper surface opposite the mounting surface, a pair of opposing end surfaces adjacent to the mounting and upper surfaces, and a pair of opposing side surfaces adjacent to the mounting surface, the upper surface, and the end surfaces. End portions of the lead-out portions respectively have a flat portion exposed from the body surface, a covered portion adjacent to the flat portion at at least one of the end portions covered with the magnetic portion, and the flat portion is electrically connected to the outer electrode.
