Hello-
I need a good quantity of a plastic slug tuned PC mount coil form as
follows :
OD of form- .18 to .22"
Height - 5/8"{ min} 3/4" optimum
Slug Mat'l - used at 28 thru 116 Mhz.
These coil forms are mounted by simply pushing them thru a tight
fitting hole in PC board until the small base flange contacts underside of
board. The base flange size is not critical as I trim it down to just barely
bigger than the form.What you end up with is just a coil form rising above
the board and it is wound in place.There are no terminals needed.
I have been using surplus coils that I removed a set of windings from
and trimmed away the bases.They worked OK but old cement from windings did
cause some winding slowdowns.
I used to see bags of these type coils advertised in surplus catalogs,
etc, but for the life of me cannot locate any now. I can use up to 200-300
of them.
Thanks, WA5THJ
