Subject: LF: Toroid inductor winding chart???

Does anyone have a chart or a link to an online chart for winding toroids to a specific inductance? The specific cores are T50-43 but if there is a universal chart available, that would be nice to keep around the shop for future inductor winding.

The toroids will be wound with Litz wire so we don't want to waste any expensive Litz if possible.

Thank you,

Mike
