ferriteschematicssymbol [~]
I saw this symbol in the schematic of the ADPD2140z eval board. From what Ive seen online, ferrite bead symbols are usually slanted rectangles with right angled corners. This is slightly different, but is this also a symbol for a ferrite bead?
Here is an image of the component E1 in question:
If I'm looking at the correct symbol, that's a feed through capacitor.
They are common on RF devices where they allow wires to enter a shielded enclosure.
Looking at the picture from the link you gave here they are:
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.
Best Answer
Yes, it is indeed a ferrite bead symbol.
There are standards for component symbols, however as with all standards, people choose not to follow them, and instead make up their own variants (obligatory XKCD Comic).
