I'm trying to setup a DC filter to remove noise that's is entering an amplifier circuit. It's just standard line current noise at 60Hz. I can't figure out how on the other hand how to calculate the necessary values to pick an inductor that will do the job.
The DC power in is 16V @ 4A, DC Resistance just using Ohms Law is 4Ohms.
To pick an inductor I need to know the inductance in Henry's, and a few things I have know nothing about:
Q @ Freq
Self Resonant Frequency
Most likely I'm going to go with a Ferrite core but I'm not 100% on that yet, but I think it would work best.
What do you guys think?
