Abstract
A laminate-type electronic component includes has a first coil and a second coil, and the number of turns of the first coil is smaller than that of the second coil due to a positional relationship between input-output electrodes. As a result, the thickness of an outer layer on the first coil side is increased, that is, the magnetic path cross-sectional area of the outer layer is increased. Thus, the inductance of the first coil is decreased. The thickness of the outer layer on the second coil side is decreased, that is, the magnetic path cross-sectional area of the outer layer on the second coil side is decreased. Thus, the inductance of the second coil is decreased.
Claims11
A laminate-type ceramic electronic component comprising:
- a laminate body including a plurality of ceramic layers and a plurality of coil conductors that are laminated to each other in a lamination direction;
- and
- first and second coils including the plurality of coil conductors;
- the first and second coils being arranged in the lamination direction of the ceramic layers while the axial directions of the first and second coils are substantially coincident with the lamination direction of the ceramic layers:
- a distance T1 between the first coil and a surface of the outer layer of the laminate body nearer to the first coil and a distance T2 between the second coil and a surface of the outer layer of the laminate body nearer to the second coil in the lamination direction being different from each other.
