Abstract
Disclosed herein is a coil component that includes a first conductor layer having first and third planar spiral coils and second conductor layer having second planar spiral coil. The first planar spiral coil is positioned on an outer peripheral side of the third planar spiral coil. The first planar spiral coil has a pattern width larger than that of the third planar spiral coil. The second planar spiral coil is offset to the third planar spiral coil side in a plan view.
Claims14
A coil component comprising:
- a plurality of conductor layers stacked one on another through insulating layers and having first, second, and third planar spiral coils with a same number of turns;
- first, second, and third terminal electrodes connected respectively to one ends of the first, second, and third planar spiral coils;
- and
- fourth, fifth, and sixth terminal electrodes connected respectively to other ends of the first, second, and third planar spiral coils,
- wherein the plurality of conductor layers include first and second conductor layers stacked one on another in this order,
- wherein the first and third planar spiral coils are formed in the first conductor layer,
- wherein the second planar spiral coil is formed in the second conductor layer,
- wherein the first planar spiral coil is positioned on an outer peripheral side of the third planar spiral coil,
- wherein the first planar spiral coil has a pattern width larger than that of the third planar spiral coil, and
- wherein the second planar spiral coil is offset to the third planar spiral coil side in a plan view.
A coil component comprising:
- a first conductor layer having first and second coil patterns;
- and
- a second conductor layer located above the first conductor layer, the second conductor layer having a third coil pattern,
- wherein each turn of the first coil pattern is positioned on an outer peripheral side of an associated turn of the second coil pattern,
- wherein each turn of the third coil pattern is positioned on an inner peripheral side of an associated turn of the first coil pattern and positioned on an outer peripheral side of an associated turn of the second coil pattern,
- wherein a width of the first coil pattern is greater than a width of the second coil pattern, and
- wherein a radial center position of each turn of the third coil pattern is offset to an inner peripheral side with respect to a radial center position of a space between associated turns of the first and second coil patterns.
A coil component comprising:
- a first conductor layer having first and second coil patterns;
- and
- a second conductor layer located above the first conductor layer, the second conductor layer having a third coil pattern,
- wherein each turn of the first coil pattern is positioned on an outer peripheral side of an associated turn of the second coil pattern,
- wherein a width of the first coil pattern is greater than a width of the second coil pattern,
- wherein each turn of the third coil pattern overlaps an associated turn of the first and second coil patterns, and
- wherein an overlap amount of the first and third coil patterns is smaller than that of the second and third coil patterns.
