The frequency dependent features of the gapped toroidal construction are extracted empirically about a bandwidth that exceeds 30 MHz. The analysis is difficult due to non-linear flux… For typical-manner noise, you may have to reconsider the way you've grounded the procedure to forestall capacitive sound coupling to the PCB.
