Please help make sense of the following specs.  I would like to wind inductors to use on the Firstwatt F5 power supply
The part I don't get is the Inductor radius measurement.  Is this inner or outer?

These seem pretty huge, is there a more compact option? 


Value:  2mH

DC resistance 0.42 Ohms

Inductor height 0.88 Inches ( 22.31 mm)

Inductor radius 1.76 Inches ( 44.63 mm)

No. of turns 125

Wire diameter 0.058 Inches ( 1.48 mm) 15 AWG

Power 450 Watts

Wire length 132.0 feet ( 40.2 m)


Or am I just wasting my time and should just use the resistors.
