Many of the schematics I've seen in reference schematics use an the symbol of an inductor as the symbol for a ferrite bead (makes sense).
But I've also seen other variants of it as well. I don't have the IEEE 315 document, but I know that there are somethings that we do in North America that isn't exactly IEEE standards.
Bonus question: Is there a document or source that lists North American standard symbols ?
Best Answer
The IEEE is a US-founded organization that has brought "North American standards" to much of the rest of the world. Any non-IEEE symbols being used in North America merely demonstrate our inability to fully standardize those symbols on the continent. A copy of IEEE 315 if anyone is looking.
The alternative to IEEE is the Europe-based IEC, and I could not find any information on their preferred standard for a ferrite bead.
The person who assembled those images had no final answer either; simply put, the IEEE's is the only ferrite bead standard I was able to confirm.
