Tunable RF Inductors – 148 Series
Document 111
Specifications subject to change without notice.
Document 111
Revised 11/26/02
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 guarantee
a constant winding pitch and a consistent relationship to
the printed circuit board. Tuning is done by means of a
threaded Carbonyl J core.
Coilcraft Designer’s Kit M104 contains three samples
each of 13 standard values 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. 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.
2. L min measured with core halfway out top of form.
3. Inductance values at 50 MHz calculated from C
p readings. Inductance values at 25 MHz read at standard Q meter frequency (blue line).
4. Core material: Carbonyl J. Core length: 3/8
″.
5. Operating temperature range -40°C to +85°C.
6. Electrical specifications at 25°C.
