Ferroxcube Pot Core

I am looking for a Ferroxcube core. The description/part number I have is PH7/3.4/I-3C91. I don’t know if you sell this part?

Hello purchasing19,

Welcome to the DigiKey TechForum.
I’m sorry, but this part is not carried by DigiKey. We are unable to process a quote or order for this item.

The part number would seem very similar to, but not quite the PH7.4/3.9 form & size mentioned on p703 of the Ferroxcube data handbook.

Such things can presumably be obtained as custom items, but by definition those custom items are not going to be available from stock. Asking questions as to where the part number came from may give clues as to how it might be procured.
