摘要:
A common mode noise filter includes: a common mode filter inserted into a pair of signal lines; and a pair of capacitively coupled coils having one ends connected respectively to the corresponding signal lines and the other ends opened. According to the present invention, common mode noise can be removed by a common mode filter, as well as, differential mode noise in a desired frequency band can be removed by a pair of coils whose other ends are opened.
