Title:
積層型インダクタ及び積層型インダクタのインダクタンス調整方法
Document Type and Number:
Japanese Patent JP5008926
Kind Code:
B2
Abstract:
To adjust inductance while securing a Q value without using a conductor pattern of different kind.
The stacked inductor includes a laminate yielded by laminating a plurality of insulating layers; and a pair of external electrodes 12, 14 formed on both side surfaces of the laminate. The laminate includes conductor parts 16A to 16H. The conductor parts 16A to 16F, 16H are constructed with a pair of coils 161, 162, ... of the same shape with one ends electrically connected and with the other ends electrically connected so as to be connected in parallel. The conductor part 16G is constructed with one coil 1613. The external electrode 12, the conductor parts 16A to 16H, and the external electrode 14 are connected in series in this order. For this, inductance of the conductor part 10G is larger the an combined inductance of the other conductor parts 16A to 16F, 16H.
