Andrey Sviyazov andreysviyaz at gmail.comHi Jean-Samuel. Yes, you are all right and you can order TDK - MPZ1608S601A instead of MLB-160808-0600PL. And also possible to use 3 times cheaper FBMH2012HM121-T, 0805, 2.5A<http://ru.farnell.com/taiyo-yuden/fbmh2012hm121-t/ferrite-bead-0805-32mohm-2-5a/dp/8186421> instead of MLB-201209-0120PU.
