Hi Andrey,
Thank you very much for your reply.
Now, I better understand.
You are all right. I do not have anything as high current as
MLB-201209-0120PU at a lower price.
However, I have a 0603 600 ohm 1A bead, as MLB-160808-0600PL, at a much
lower price.
What do you think about this component (TDK MPZ1608S601A)?
Best regards.
Jean-Samuel.
:-)

Hi Jean-Samuel.
If Farnell better for you, then please order exactly
MLB-201209-0120PU<http://ru.farnell.com/mec-marcom/mlb-201209-0120pu/fer…
and
MLB-160808-0600PL<http://ru.farnell.com/mec-marcom/mlb-160808-0600pl/fer…
.
They are HI_CURRENT beads and it is really required.
Please find attached here new SCH and BOM files with new part numbers
and links.
Best regards,
Andrey Sviyazov.
