    Design Notes

    • Common-mode impedance rises with frequency, so the part is chosen by the band it must suppress.
    • Differential-mode noise is not addressed by a common-mode choke alone.
    • DCR adds to the supply drop — check it against the current budget.
    • Winding capacitance sets how well high-frequency noise is blocked.
    • At 0.3 ohm DCR, voltage lost across the choke grows with load current.
    • Keep the working current under 370 mA; saturation collapses the impedance.
