7 mm Tunable RF Coils – 146, 150
Coilcraft tunable coils provide the compactness of a 7 mm
coil and the low drift reliability of an insert molded coil.
Standard inductance values range from less than 0.05
µH to over 0.5 µH. 150 Series coils with a tap are also
available to meet specific requirements.
The windings of these economical coils are precision
molded into a single piece of polypropylene for mechani-
cal and electrical stability. Optional plated brass shield
cans with solderable tabs provide integral shielding and
additional mounting stability.
These parts can be odered without cores for use as
fixed inductors.
Coilcraft
Designer’s Kit M302
contains samples of all
standard 7 mm and 10 mm tunable inductors. To order,

1. To order fixed inductance parts without cores, eliminate the “J08”, e.g.
150-01L or 150-01SL
2. Inductance and Q readings taken on Boonton 260-A Q meter with 16
AWG tinned copper 1/2″ long soldered along leads and bent at 90°
1/4″ down from standoffs.
All inductance values greater than 0.1 µH read at recommended Q me-
ter frequency.
All inductance values below 0.1 µH calculated from readings taken at
50 MHz.
L min measured with core halfway out top of form.
Average current for a 40°C rise above 25°C ambient.
Core material: Carbonyl J; Core length: 1/4″
Taps available in 150 series parts at 1/8, 3/8, 5/8 and 7/8 turns.
Operating temperature range
−40°C
to +85°C.
Electrical specifications at 25°C.
