Document 108-1 10 mm Tunable Coils–142, 143, 144 Series 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 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 fixed inductance parts without cores, eliminate the “J08” or “J12”, e.g. 144-01L or 144-01SL. 2. Inductance and Q readings taken on Boonton 260-A Q meter with 16 AWG tinned copper 1/2″ long soldered along leads and bent at 90° 1/4″ down from standoffs. All inductance values greater than 0.1 µH read at recommended Q meter frequency; those below 0.1 µH calculated from readings taken at 50 MHz. 3. L min measured with core halfway out top of form. 4. Q min measured at L nom at 40 MHz. 5. Average current for a 40°C rise above 25°C ambient. 6. Core material: Carbonyl J Core length: 142 Series - 1/4″ 143, 144 Series - 3/8″ 7. Taps available on 144 series parts at 1/8, 3/8, 5/8 and 7/8 turn increments. 8. Operating temperature range −40°C to +85°C. 9. Electrical specifications at 25°C.
