Abstract
A coil component includes a first coil and a second coil that magnetically couples with the coil and causes a negative inductance to be generated. The coil component further includes an electrode that is provided at a position adjacent to or in the vicinity of a port of each of the first and second coils.
Claims18
A coil component comprising:
- a first coil;
- a second coil that magnetically couples with the first coil and causes a negative inductance to be generated;
- and
- an electrode that is provided at a position adjacent to or in a vicinity of a portion of the first coil and a portion of the second coil and is grounded;
- wherein
- a spacing between the electrode and an adjacent wiring line of at least one of the first coil and the second coil is smaller than at least one of a spacing between adjacent wiring lines of the first coil and a spacing between adjacent wiring lines of the second coil.
