Fair-Rite makes at least 20 different ferrite materials, each tweaked
for specific and often very different performance characteristics for
product applications. They range from large and small power handling
over various frequency ranges (think power supplies, controllers), to
linear RF small and large power and frequency ranges, to EMC
suppression, again in various frequency ranges and power handling.
The Fair-Rite catalog, something like 300 pages, can be downloaded from
their website as a pdf. To find it, click on something like order a
catalog, and poke around until you find the link. It is VERY detailed,
with a ton of engineering data. It's possible to learn a LOT about
ferrites from studying it. The first 30-40 pages have detailed data on
each mix, much of it in the form of plots.

#### L5 is powdered Iron, #2 mix (red core, MU=2)..... and L5 is used
only on 160m.
