Thank you guys for your in depth comments on Laird. This now circles
back to what I attempted to say in the beginning. I do not believe we get
all the information we need as radio guys just from the data sheets. It
has been the collective wisdom of many including the posters here and
mentors we have worked with and suppliers we have trusted that have
in the long run provided the information we as radio guys really need in
ferrite. I understand Jims work and I understand Toms comments. My
point was we should not just throw Laird to the wind as a supplier
because of lack of data. There are sometimes applications for ferrites
that not all suppliers do well as you both have pointed out, however in
my case at this point without doing years more of research I have found
an off brand ferrite (not Laird) that worked better for my application than
any of the many brands I tested. The recomendation was from an
experienced toroid winder.
I would not choose Laird as a supplier for either Toms or Jims examples,
however they do make pretty good and inexpensive transformers for
wideband high level preamps as both W7IUV and K8ZOA have pointed
out. I would bet Beverage transformers too.
We likely are all saying the same things just a different way.
