Document 108-1 Document 108-1 Revised 09/18/08 10 mm Tunable Coils–142, 143, 144 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.
