Jean-Samuel Najnudel - BJT PARTNERS SARL jsn at bjtpartners.comHi Andrey, Thank you very much for your help. I will forward this to the fab. Yes, you are all right, the FBMH2012HM121-T price is much better than the MLB-201209-0120PU. However, availability on Farnell France is not as good as the MLB-201209-0120PU. Price difference is quite big but we only use 5 beads per boards. Difference makes only about 1 euro per board. I will let the fab decide between these 2 references. Best regards. Jean-Samuel. :-) On Wed, Jul 4, 2012 at 4:30 PM, Andrey Sviyazov <andreysviyaz at gmail.com>wrote: > Hi 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. > > Best regards, > Andrey Sviyazov. > > > > 2012/7/4 Jean-Samuel Najnudel - BJT PARTNERS SARL <jsn at bjtpartners.com> > >> Hi Andrey, >> >> Thank you very much for your reply. >> Now, I better understand. >> >> You are all right.
