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.
