MOTM

One can also get the muRata BL01RN1 from alliedelec.com:

muRata BL01RN1-A1D2B 70ohm@100MHz body length 5mm
Allied 711-4101 $0.45 ea

Also at mypioneer.com part# BL01RN1A1D2B  These are listed at 6 cents each
(!) but you have to call first.  BTW, I believe the -A1D2B part is the same
as the -A62 part, just different packaging.

A few other ferrite bead options I've dug up:

Fair-Rite 2743002112 133ohm@100MHz body length 8.9mm
Mouser 623-2743002112

Fair-Rite 2743004112 110ohm@100MHz body length is 7.6mm
Mouser 623-2743004112

Panasonic EXCELSA39 110ohm@100MHz body length is 9.3mm
Digikey P9818BK-ND

These Fair-Rite and Panasonic parts provide superior suppression to the
muRata bead, albeit with a tighter fit due to a longer body length.  Since
most PCBs tend to have a lead spacing of 10mm for beads, the EXCELSA39 and
2743002112 leads will have to be bent inward slightly, and therefore these
beads will not sit flush on the PCB.  Panasonic makes a smaller EXCELSA35,
but it's not as good as the muRata.  The Fair-Rite 2743004112 is what I plan
to use for my projects.  Unfortunately Mouser does not have them in stock at
the moment.
