10 mm Tunable Coils  
142,143,144 Series  
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,  
contact Coilcraft or visit http://order.coilcraft.com to  
purchase on-line.
