Anyone tried Miller inductors?

Anyone tried these for audio gear, specifically EQ's?

They are not expensive & widely available from Farnell & Newark.

500mH inductor : 70F501AF DCR 736 ohms - too high for EQ's?

Miller capacity ...
??? xvlk

The self res is high enough since a 500 mh coil would be operating down at 100 hz or below, so your ok as far as capacitance. I am woried about the dcr. Seems like it would upset the Q of the curve, flatten it out too much. Maybe a simulation would be in order.

Miller coils are like Allen Bradley resistors: they are (or used to be) the plain-vanilla standard of the industry. Any good radio experimenter had a set of drawers of Miller coils.

Your problem is that the the inductance, current, and DCR values we need in audio are very small-demand. As you note they don't have the higher inductances and the medium inductances have high DCR and low current ratings. (In audio, an iron-core choke should not get an audio current anywhere near the DC current rating of the choke.)

How about those as EQ inductors?

pretty low DCR!!! Should need extra shielding thought, but nothing really fancy.
