Yes, sir...🙂
I have found on the Murata website a macro file for that chip bead, looks much better...😉

great !
maybe you can share that model, so everyone can learn how to model a ferrite bead.
best,

I don't get that R2 thing.No more then the resistance of the wire in the bead.
If you do, why not include a rsistance for every wire in the circuit ?

if it is significant, you should indeed do so. If it is not significant, forget it, it is extra work and real engineers are lazy; they think before they act.
Than used in a comparison is written with an a. Then written with e refers to time.
enjoy the weekend,

English is a mess, are, war, waste, I am, all "a" all different.
If you use a mess you get a mess.
Nice weekend to,

Mona probably knows that as she is from Flanders 🙂
It seems most native speakers do not know this. Same with "should of" instead of "should have", "they're car" instead of "their car", "I don't know weather that is OK" instead of "I don't know whether that is OK" etc. It is not the foreigners that mess up their language, they seem experts in doing so themselves 😉
And eh... too is with 2 x o ..... Like "I am going to Antwerp" and "it is too much". To = naar, too = te. Yeah, language fanatic here. Sorry.

Thanks Guido!
This chip bead has a little influence only in the region of about 10MHz, and does not eliminate OPA oscillations...
