"The only thing that seems potentially
undesireable about these materials is that they both have low curie temps
(125 and 120 deg.C) so that it would be very important that these chokes
not get hot."
	Before going to the trouble of building ferrite-cored
devices make sure you calculate the maximum flux density at
the operating voltage and frequency.  Formulae to do this, plus
data on the various ferrite materials, is on the amidon site
whose CORRECT addres has been published here by several people.
Make that address.
