共模扼流圈
摘要：
本发明提供共模扼流圈。该共模扼流圈具有彼此磁耦合的第一线圈导体和第二线圈导体；第三线圈导体，该第三线圈导体串联地电连接到该第一线圈导体，并基本不与该第一线圈导体磁耦合；第四线圈导体，该第四线圈导体串联地电连接到该第二线圈导体，并基本不与该第二线圈导体磁耦合；第一接触导体，用于将该第三线圈导体与该第一线圈导体的内端相连接；以及第二接触导体，将该第四线圈导体与该第二线圈导体的内端相连接。该第三线圈导体和该第四线圈导体基本不磁耦合，并且以规定的中心线为基准具有线对称关系。
摘要（英）：

A common mode choke coil is provided with first and second coil conductors that are magnetically coupled to each other, a third coil conductor that is electrically connected in series to the first coil conductor and substantially not magnetically coupled to the first coil conductor, a fourth coil conductor that is electrically connected in series to the second coil conductor and substantially notmagnetically coupled to the second coil conductor, a first contact conductor for connecting the third coil conductor with the inner end of the first coil conductor, and a second contact conductor forconnecting the fourth coil conductor with the inner end of the second coil conductor. The third coil conductor and the fourth coil conductor are substantially not magnetically coupled, and are in a linear symmetrical relationship based on a prescribed center line.
