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,

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

readings. Inductance

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

5. Core material: Carbonyl J. Core length: 3/8″.

6. Operating temperature range -40°C to +85°C.

7. Electrical specifications at 25°C.
