[Amps] fiberglas tape

[Will Matney]

I think what some may be refering to is that thin box wrapping tape that has the strands (filaments) in it, say about 3/4" wide. Most magnetics manufacturers use Kapton tape which Mouser and others stock. It has an orange-clear color to it, and I think 3M makes it. Not all cores need to be taped though. Most ferrite cores for RF circuits just use magnet wire or wire with teflon insulation, nothing more. The only reason to use it would be if the core is electrically conductive.

Best,

Will
