With an overall height of only 0.300″, these tunable
coils are ideal for applications where low-profile circuit
boards are essential.
The windings are precision molded in plastic to guaran-
tee a constant winding pitch and a consistent relation-
ship to the printed circuit board. Tuning is done by
means of a threaded Carbonyl J core.
Coilcraft Designer’s Kit M304 contains three samples
each of the values shown plus 20 values from the
132 Series of low-profile, high Q fixed inductors. To order,
