Part Number: TMS570LC4357
Other Parts Discussed in Thread: TMS570LC4357

The picture below is a schematic of the Hercules TMS570LC43x Development Kit.
I want to know if I need the E1 (NFM21PC474R1C3D) in red square.
I would like to know if there is any problem in using Z0805C330BPWST Bead to replace E1 (NFM21PC474R1C3D).

Hello Bake,

NFM21PCx is a EMI filter. The ferrite bead can suppress the high frequency noise. You can use FB in your schematics.

Hello ! Wang.
Thank you for your answer.

The tms570lc4357 data sheet does not mention high frequency.
Which band of frequencies should be filtered?
