Seeking ferrite cores, a good distributor with many parts?

configurations, with different sizes and types of ferrite cores. For starters just E-cores

some obscure types, but none that have different E-cores with different AL values (airgaps)

to arrive at the desk.

Yes, their web site is crummy but the company is great and support is excellent (and fast):

If you need a contact there let me know and I'll dig it out. As for air gaps, vendors might offer a few (very few) standard values that suit flybacks but typically you have to make your own. Either get some shim material or find a local shop that can grind down the center pod without splintering too much off of the ferrite. If you grind it yourself _never_ do that without eye protection. I knew a guy who did something like that without, he didn't lose that eye but said the pain was terrible.

Here is a distributor, these guys are good. You should be able to get some samples if they don't have stock.

In addition to the others,

Amidon has a good catalog, but you'll only see the products they chose to list. Their ferrites are primarily Fair-Rite or Magnetics Inc., while their powdered irons are from Micrometals.

Adams, Elna and most others *don't* have an online catalog, at least not in the way we're familiar with, like Digikey and them do. You'll have to go back and forth a few times between manufacturer's product listing, checking that they even make the kind of thing you're looking for (shape, material, A_e, gap, etc.), then checking if that part is carried and in stock.

The largest manufacturers carried by these companies are usually among: Fair-Rite EPCOS/TDK Ferroxcube Magnetics Inc. (ferrite, powdered iron, stripwound) Micrometals (powdered iron) VAC and HMG (amorphous/nanocrystalline)

Fair-Rite has great sample kits.

These folks

are a great distributor.

As does MuRata (resistors, too).

Thank you all for some good links ;-)

Most design work will not allow 'a lot of different configurations', based on some simple preliminary calculations, on paper.

You'll get more support and useful samples from suppliers if you have a ballpark idea of your actual needs, for a specific application.

I bought a small quantity of Ferroxcube EP13-3E55-A100 cores from them - "low distortion" cores for ADSL, though that's not what I'm using them for - and they were quick and helpful.

I would have posted this earlier, but my file swapping onto my new computer didn't work as well as it should have and the relevant bunch of e-mails didn't make it on the first attempt.
