1. 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.
