N27 and N67 are similar also. N30 is a higher permeability material, not really intended for power applications. Fair-Rite 78 grade is also very similar.

Hello ....... I am looking for a source to buy 3C90 (or 3C85) toroids, 58mm diameter. Up til now I can only find 'Spoerle' , but I have to buy at least 36 of them............ Is there any other compagny that have these large cores available in lower quantities?? Preferable in Germany or the Netherlands. Maybe there is a alternative by using Epcos cores? Material N87?? or N30?? Anyone?? 73 Dick , PA4VHF (I know about using TV-cores etc, but just wonder if there is a way to get these nice ringcores)
