FERROXCUBE - ETD29/16/10-3C90 - FERRITE CORE, ETD, 3C90 5 5 1 1
Glad I found these I am happy to see that Newark carries a range of ferrite products from Ferroxcube. I have used other ferrite brands and found them all to be of about the same good quality. These are nice for making custom inductors and transformers. This is a common size and material for small switching power supplies. October 25, 2014
