摘要： An inductor includes discrete magnetic core pieces fabricated from different magnetic materials having different magnetic properties. An inverted U-section conductive coil includes a top section and first and second legs to establish a surface mount connection to a circuit board, and the discrete magnetic core pieces are assembled around the inverted U-section conductive coil. The first and second discrete magnetic core pieces are operable to reach magnetic saturation at respectively different current loads applied to the coil when the circuit board is energized, imparting multiple steps of inductance rolloff response to a range of current loads.

摘要： A coil component that includes a core, a first wire, and a second wire. The core has a prism-shaped winding core part. The first wire and the second wire are wound around the winding core part. The coil component has an overlapping winding region in which the first wire is wound around the winding core part and the second wire is wound around the winding core part on top of the first wire. The overlapping winding region includes a prescribed part in which the first wire and the second wire are wound around the winding core part in such a manner that a gap is interposed between a part of the first wire that is wound along a first side surface of the winding core part and a part of the second wire that is wound along the first side surface.

摘要： An inductor and method for making the same are provided. The inductor includes a coil that is not wound around itself. The coil may have an “S”-shape. The coil has two leads extending from opposite ends of the coil. An inductor body surrounds the coil and portions of the leads. The leads may be wrapped around the body to create surface mount leads on the exterior of the inductor.

摘要： An inductor component includes a component body having a mounting surface and a top surface and provided therein with a spiral inductor wiring line advancing in the extending direction of a winding center axis. The inductor wiring line is connected to a first external electrode at a first end, and connected to a second external electrode at a second end. The component body includes: a first inclined surface connected to a first end of the mounting surface on a first side in a length direction and inclined toward the top surface as separating from the first end; and a second inclined surface connected to a second end of the mounting surface on a second side in the length direction and inclined toward the top surface as separating from the second end. The winding center axis extends in a direction parallel to the mounting surface and perpendicular to the length direction.
