These Coilcraft variable inductors are precision molded
in plastic to ensure constant winding pitch and a con-
sistent relationship to the printed circuit board.
Extremely economical, even in small quantities, the
coils come in standard inductance values from 0.05 µH
to 1.5 µH. 144 Series parts are also available with a tap
to meet specific requirements.
Tuning is done by means of a threaded powdered iron
core with a hex socket for easy, positive adjustment.
Plated brass shield cans with solderable tabs are optional.
These parts can be odered without cores for use as
fixed inductors.
Coilcraft Designer’s Kit M302 contains samples of all
standard 10 mm and 7 mm tunable inductors. To order,

Resistance to soldering heat: Wave solder only. Recommended maximum
board surface temperature of 168°C (334°F) for no more than three seconds.
Pre-heating is recommended to minimize time over the solder nozzle.
Terminations: Series 142 and 143 leads: Tin-silver over copper
Series 144 leads: Matte tin over copper
Shield can tabs: Tin-silver over nickel over brass
