Document Type and Number:
Japanese Patent JP6848592
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce difference of transmission characteristics between signal lines, in a coil component where three or more coils are magnetically coupled with each other.SOLUTION: A coil component includes spiral coils C11, C12 connected in parallel between terminal electrodes E1, E2, spiral coils C13, C14 connected in parallel between terminal electrodes E3, E4, and spiral coils C15, C16 connected in parallel between terminal electrodes E5, E6. The spiral coils C11, C13 are arranged to be coupled magnetically with each other, the spiral coils C12, C15 are arranged to be coupled magnetically with each other, and the spiral coils C14, C16 are arranged to be coupled magnetically with each other. Since combinations of two signal lines are created from three or more signal lines, and each combination is coupled magnetically, variation in the coupling characteristics between respective signal lines can be reduced.SELECTED DRAWING: Figure 2
