altium library ferrite
If you want to use a special symbol in the schematic for a ferrite bead, draw it yourself - that's what the library editor is for.
Generally, what people call a ferrite bead in a surface mount environment is really a surface mount inductor. True ferrite beads are just that, a ferrite ring that is slipped over a wire. You seldom see those on a PCB.
You can use an inductor symbol, and use the comment field to describe it according to your specific needs.
