Default inductor calculator

I have come across an inductor calculator for the zobel network on this forum way back. Life is always like that, when you don't need it, it's flashing up here and there, but when you need it, it's nowhere to be found. Does anyone remember where to find it?
Tks.

It's not really critical anyway... usually wrapping 22SWG enamelled wire around the body of a 10 ohm 2W resistor is about right

Hi guys,

I want a 7uH coil so I punched in the #s.

It says 40.05 cm, it's cm not mm. Am I using the calculator correctly? Or am I just so dumn?


I am actually try to make a coil for the quad 303. Could it be that it is not a air coil?

Interval between turns is '0' and not the wire diameter unless you want that for some reason. Use "several layers" and set a coil length.

The length will be reduced if you increase the diameter of the coil( because the inductance is proportional to the product L*d) and if you have little spacing between turns.
For 20 mm diameter and spacing of 0.5 mm i get 6 cm length
