Hello again:

Please, you could tell me what are the technical data of the ferrite L1 in the USB version.
I know it's possible to put a bridge, but I would put this component.

Thanks and best regards.

for the ferrite bead, ftdi recommended this one : http://www.steward.com/web_info/CADPrin ... R-10-A.pdf

<<A ferrite bead is connected in series with the USB power supply to reduce EMI noise from the FT245R and
associated circuitry being radiated down the USB cable to the USB host. The value of the Ferrite Bead
depends on the total current drawn by the application. A suitable range of Ferrite Beads is available from
Steward (www.steward.com), for example Steward Part # MI0805K400R-10.>>
(found in : http://www.ftdichip.com/Documents/DataS ... FT245R.pdf)

but this part is now obsolete !

this one is ok for replacement :
