10mmTunableCoils–142,143,144Series
These Coilcraft variable inductors are precision molded
in plastic to ensure constant winding pitch and a consis-
tent relationship to the printed circuit board.
Extremely economical, even in small quantities, the coils
come in standard inductance values from 0.05 H to
1.5 H. 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 M102 contains samples of all
standard 10 mm and 7 mm tunable inductors. To order,
contact Coilcraft or visit http://order.coilcraft.com to
