Thought this may be of interest to those reading the recent
threads on 31 mix ferrite
I have no pecuniary interest in the matter

------------------------------------------------------------------------
I was in the process of making a group buy for our local radio club
of some -31 Mix Ferrite clamp on beads
that will fit tightly on RG-213 size coax and also be good for smaller
cables that I could
thread thru several times for efficacy. ( Hole is approx 0.400" )
I discovered that Mouser Electronics now sells at least this one
particular -31 Mix Ferrite
bead that works well for RFI problems per Jim Brown's recommendations in
the past
on this reflector. ( These do well in place of 43 or 77 mix and I now
use this
mix from 160 thru 6 mtr band to resolve RFI probs with good results )
They are $2.70 in small quantity but drop to $1.70 for 100 pieces,
so get together with
a few buddies or your local contest or DX club and snap up the discount !
You can get to Mouser's order page by typing
0431167281
in Google search and it will be the first hit you get
or go to www.mouser.com and enter part number 623-0431167281

Fair-Rite FERRITE SNAP CASE - RoHS: COMPLIANT
*NOTE: Important !*
I found one anomaly with these and that is that if you do use them to
snap directly onto
RG-213 type coax ( approx 0.400" Diameter) or coax with the same
diameter, the plastic shell that comes
with the bead has a slightly* smaller *diameter than the hole in the
ferrite bead itself and will not allow
you to clamp the bead onto the coax until you take a pair of diagonal
cutters and trim the
plastic making the hole bigger. Just a nuisance for now as I have
alerted Mouser and Fair-rite
and hopefully they will use the correct plastic shell in the future.
Also, if you would like to buy 2.4" Round ( Donut ) type, (
Fair-Rite P/N *2631803802 )
*and these are really great for really tough RFI problems, you can order
them from Dexter Magnetic Technologies
I am not sure what their minimum order is but when I do my group
buys of 100 pieces
I have gotten a piece cost down near $3, though I hear the price will be
rising sharply soon
due to the price of one of the materials use in making the -31 MIX - (
like going to $4.28 ea in 100 Qty ! )
