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 C_preadings. Inductance

values at 25 MHz read at standard Q meter frequency (blue line).
