ABSTRACT:
An integrated and drop-in EMI filter that features common-mode and differential-mode noise filtering capabilities is disclosed. The common-mode portion and the differential-mode portion of the filter are independent of each other in that the two filter portions may be made out of different ferrites, also in that, the an increase in the filtering capability in one mode, such as having an increased number of turns in the winding, would not affect or reduce the filtering capability of the other mode, such as reducing the overall throughhole depths a conductor travels.
