Hi to all,

I have a doubt about what type of ferrite beads should I buy, in many projects like filters or others you can use ferrite beads instead 10ohms resistors, but ferrite beads are in Henrys, wich is the replace for this resistors of 10 ohms in Henrys?, what ferrite beads should I buy?

is that a good option?

Thanks in advance.

Those seem to be inductors with a ferrite core, you just need simple ferrite beads like this:

(I guess they are basically inductors too)

Thanks PHOBoS, I think this is probably a FAQ.
