Tnx to a tip, fair rite makes this huge snap on, pn Fair-Rite Part Number
2631181381
This thing has an ID of 1.394 inch..which is just a hair less than the 1.4 inch
of normal type 31 cores.
However, this monster is 2.5 inchs tall... and the eq of 5 x normal
toroids..which are only .5 inch tall.
Dunno what it cost, but it’s a quick fix for a lot of applications. It has
the same Z as 5 x normal toroids.
Yes. That part number applies to HALF of a clamp-on, and without the
plastic clamping assembly. So to make that a choke, you must use two of
them AND clamp them very tightly together. This is a new part, within
the last year or so. I ordered a bunch of them for a group purchase,
because the data sheets did not show that it was not a complete
clamp-on. We returned them. It's a deal that was too good to be true.
And it's not cheap -- a pair of these parts costs as much as five cores,
and you still don't have a clamping mechanism. At the very least, this
requires a couple of very robust Ty-Wraps.
