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.
