Abstract:
In a common mode filter, at least one common mode filter portion is provided for removing a common mode noise, and has a first terminal pair configured to include first and second terminals connected to first and second external terminals, respectively, and has a second terminal pair configured to include third and fourth terminals connected to third and fourth external terminals, respectively. The filter includes an inductor circuit including at least two inductors that are connected in parallel to the first terminal pair of the common mode filter portion and are connected in series to each other, and an external terminal connected to the connection point of the at least two inductors. The external terminal is for being directly or indirectly grounded.
