Can a Toriod * transformer be Glued to a heat sink??? * The *Toroid
will be JB welded to the heat sink.

The toroid will be wound *with a 30 degree gap *between the start of
the winding to the end of the windings * the toroid will ( winding
gap) *be glued at that that point *vertical position * the windings
will be about 1/4 inch above the heat sink.

Comments???


Are you trying to heat sink the transformer? That's a mistake. The
glue will be an insulator, not a conductor!

If you're just physically mounting it, a good stiff bolt running
through the center, with some rubber isolation, is how I always see it
done.

==================
A toroid carrying a RF signal should never get hot ......if it does there is
a serious design problem.
