Document Type and Number:
Japanese Patent JP6664661
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve such a problem that an electromotive force by an inductor is generated as noise in the pattern of a circuit board, and adversely affecting the mounting circuit on the circuit board.SOLUTION: An electronic circuit device includes a pair of inductors arranged to generate magnetic fields in opposite directions during electrification, and a predetermined signal lines substantially affected by electromagnetic noise of the inductors. The pair of inductors are arranged so that the predetermined signal lines become substantially plane symmetric with respect to a segment orthotomic surface orthogonal to the segment, at the midpoint of the segment connecting the centers of the pair of inductors.SELECTED DRAWING: Figure 2
