I want to buy a 1mH inductor. I am just making a basic LC filter and I see that there are "common mode" inductors.
I found one here with a data sheet: http://www.mouser.com/ds/2/355/DS_EV-EHseries_20110616_web19-8801.pdf
The inductor is 1mH and "common mode". Can I use this inductor to give me 1mH?(it meets my current rating too)
There are four legs on it as well. Will only using two of them give me half the inductance?
