100 C was an example.  It doesn't matter if it is 50 C or 30 C or 2000 C.  I wan't using it as literal.  The fact is that supressor resistors operate at elevated temperatures ABOVE 25 C.  Their dissipation specs are rated at 25 C.

I guess you don't read all of the postings that get put to the reflector.  Check the archives.  I tell my story at least once.  Do a search on "4-1000."
