Hi all,
I want to ask a question about the ferrite beads we use as rf chokes at dc power lines. These chokes should be open circuit for ac signals. However, I coulnd't get this feeling when i looked through the datasheet for chip ferrite beads of muRata.
At resonances the impedance of the choke is in the range of 100-1000 ohm. How can such a small impedance be open circuit to ac signals, I couldn't understand?
Thanks and best regards,
