Hello,
I'm designing an LC-filter for my project. It is 7pol low-pass Butterworth with corner frequency of 20MHz. After calculating I'm getting inductor values of ~1..3uH.
Looking in my Mouser catalog I can see that for such inductors the test frequency is usually ~7-10MHz. It's often 25MHz for lower values (tens of nanohenries). Do I need to derate inductance given at lower frequency and if so what's the procedure?
Thank you,
Oleg.
