Tunable RF Inductors – 148 Series
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,
contact Coilcraft or visit http://order.coilcraft.com.

1. To order fixed inductance parts without cores, eliminate the “J12”, e.g.
148-13L.
2. Inductance and Q readings taken on Agilent/HP 4342-A Q meter with 16
AWG tinned copper 1/2″ long soldered along leads and bent at 90° 1/4″
down from standoffs.

3. L min measured with core halfway out top of form. L max measured with
core centered in the windings.
4. Inductance values at 50 MHz calculated from Cp readings. Inductance
values at 25 MHz read at standard Q meter frequency (blue line).
