Title:
COMMON MODE NOISE FILTER
Document Type and Number:
WIPO Patent Application WO/2018/066405
Kind Code:
A1
Abstract:
A common mode noise filter is provided with a non-magnetic body portion, and first to third coil conductors formed in the non-magnetic body portion. The second coil conductor is disposed in a downward direction from the first coil conductor, and the third coil conductor is disposed in the downward direction from the second coil conductor. The first and third coil conductors are staggered in a direction orthogonal to the downward direction with respect to the second coil conductor. At least one of the first and third coil conductors overlaps the second coil conductor as viewed in the direction orthogonal to the downward direction. The common mode noise filter has the coil conductors magnetically coupled in a well-balanced manner, and does not cause a differential signal degradation.
