I have some sitting around the shop. I use them on 16ga. wire, not sure what the specs are, but I will try and post a pic, there are yours for free if that is what you need. Mavric

Thanks for all the replys!

I contacted MTL distribution and am waiting for a quote. I have had very positive experiances with amidon as well but they don't sell ETD cores sadly.

Hopefully MTL can supply what I need. I am actually surprised it is so difficult to get an E shaped ferrite core new. I would have expected more common suppliers would carry some but I see that they are hard to find in small quantities.

I've been buying mine from cwsbytemark.com. They have quite a few exotic materials in stock.

An update to all of this:

MTL distribution has not replied sadly. I had great luck with Adams magnetic and they had ETD39 and ETD44 cores, bobbins, and clips in stock.

Thanks for all the help.

I did not because they did not have quite what I needed. They seem to sell the ETD39 core but no bobbins. And they sell an ETD49 core set with bobbin but this is a little larger than what I wanted. Also, they don't seem to have the 3C94 material that I wanted.

For my application (a 250w adjustable SMPS), the ETD39 seems to fit well. I also like the ETD39 because the winding window is just over an inch wide, so I can use normal 1" wide tape.
