    You're probably going to need more than just a ferrite bead.

    Check out Amidon's specifications page on their website:
    https://www.amidoncorp.com/pages/specifications
    Under Ferrite Material, look at:
    2-14 Ferrite Beads https://www.amidoncorp.com/specs/2-14.pdf
    2-15 Beads: Material vs Freq. vs Impedance https://www.amidoncorp.com/specs/2-15.pdf
    2-16 Ferrites for RFI https://www.amidoncorp.com/specs/2-16.pdf
    2-17 Ferrite Cores for RFI Suppresion https://www.amidoncorp.com/specs/2-17.pdf

    If you want to take a shot at designing your own filter, have a look at Elsie:

    The student edition is freeware, limited to 7 poles or stages.
