Ferrite core mounting, U- brackets anywhere?

What company are you using for your cores? I last did this in the late '80's, but I was able to get all kinds of mounting clips that were springy (so as not to crack the core), and thru-hole solderable.

Like...

for one example. ...Jim Thompson

Tried FormCo ?

Check Lodestone Pacific and Robison. Both make lots of coil mounts.

The BN-43-7051 from Amidon top of the page):

The ones on page 5-43 don't look solderable and too big, our core would slosh around in there. But one of those in solderable and smaller would certainly be cool. Not sure if they'd sell to us after we celebrated their voting off of the island yesterday :-)

Thanks. Guess I'll have to ask for a catalog on dead tree since they don't seem to have a web site ;-)

Vaguely remembering... Fairite ?? ...Jim Thompson

If we absolutely have to. The risk is that a major hit during transport might cause one or both to rotate out of position.

Thanks! Will write to them right now. In case anyone else is in need:

Couldn't find Robison.

Maybe, but then likely one they make for Amidon. You can't get it at Fair-Rite. The ones in their catalog aren't quite big enough for this application:

Sometimes it makes sense to mount your inductor in a shell, with pins maybe, and solder that to the board as a component. Bigger ones sometimes have a hole for a mounting screw.

I did this little one, with a Lodesone shell...

which is surface-mountable.

Ages ago I used Ferroxcube. Art

Thanks, but looks like the don't have anything suitable under coil mounting products. But let's see what Lodestones responds.

Neat. Unfortunately most of the time I get RF projects it's higher power stuff. So I need the big old fat cores.

I had checked them. No mounts, not for such big cores.

If I have a chance tomorrow, I'll scan the Catalog into a PDF and email it. I think it's just E-I core stuff but they might have something.

I believe the Philips Ferrite core line is part of them now.

Thanks, Martin, but only if that doesn't tie you up at the scanner.

I was kind of surprised that Grainer and McMaster had nothing. I mean, you can get everything else including salt and pepper shakers there.

I've seen versions where the thick part would ratchet into the hole just like a cable tie but at a finer pitch. However, personally I do not trust plastics over the long haul. Some last forever, others give up after a few years. And you never know. Some day the elasticity has sort of evaporated and ... ping ... hiss ... *BAM*

This is for med gear so I don't want to take any chances. Machines like that can remain in service for decades.
