Greetings,

On an evaluation board I am using, at the bottom of the page, it calls for
Ferrite Beads, 600MHz, 0.5ohms. The vendor chose a particular inductor.
The specs for this inductor, BLM11A601SPT, from Murata, does have a DC
resistance rating of 0.5 ohms, but it self resonates at ~150MHz. What would
the 600MHz mean, that the DC resistance is 0.5 at 600MHz?

Alex
