These Coilcraft variable inductors are precision molded in
plastic to ensure constant winding pitch and a consistent
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 ordered 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,
contact Coilcraft or visit http://order.coilcraft.com to
purchase on-line.
