Warning

The outer diameter (OD) of the primary winding wire is so large that it may not fit within the usable winding window of the bobbin.

The transformer may not be manufacturable, on the selected core/bobbin, due to the outer diameter of the primary winding wire.

• Select a wire size with a smaller diameter.

• See Application Notes  AN-26 (-FX)  or AN-32 (-GX)  for details on wire diameter calculations.
