The invention relates to a filter assembly and a method. In particular, an electronic filter assembly includes a magnetically conductive annular body extending around a center axis, a set of magnetically conductive prongs radially extending from the center axis toward the annular body, and conductive windings extending around the prongs. The conductive windings can be disposed around the prongs instead of the annular body to assist in conduction of common mode magnetic flux, to reduce impedance of the filter assembly, and/or to more evenly distribute temperature in the filter assembly.
