Google reveals this is a "Power Ferrite <1 MHz" made by National
Magnetics Group in PA. Never heard of them. It is a MnZn matl
with u-3100. Probably not relevant for RFI suppression.
Agreed. MnZn will have dimensional resonances, which can be either very
useful (like Fair-Rite #31), or seriously limiting (most other mixes).
Lacking data comparable to what Fair-Rite provides for specific parts,
it's a science project to figure that out. The limited data suggests
power circuitry.
