Hi,
Just a question: Is ferrite bead actually an inductor? Or a filter?
Thnaks!

Larry Brasfield said:The bead can be modelled as an inductor coupled to
current paths within the bead itself. This makes it a
lossy inductor, which you can see if you look at the
complex impedance carefully.
Roger Johansson said:The core makes the inductance value a lot higher than in another straight
wire. Iron powder or ferrite cores always make inductance values higher.
It is a one turn inductor (the wire passes once through the hole ineeh said:Hi,

Jim Gregory said:I have seen op-amp audio i/ps fed from a source wire not thread just
the once, but re-looped in and out again 2 to 3 times, through the hole
of a small ferrite bead. Does this method re-filter its unnecessary HF
each pass? And is that practice kosher?

Roger Johansson said:I think it is more correct to see the bead as the core of an inductor,
the inductor is the wire going through the bead,
and it all works a a
filter, stopping high frequencies and allowing lower frequencies, as all
inductors do.
