What do I call this symbol in electronics circuit?

[smlee]

When I bumped into this symbols, I guessed they are resistors.
(the blue mesh-like symbols have 100 ohm value.)
(I've already asked this question on stackexchange but no answers yet.)






But they don't have have names, so they are not going to mounted in a PCB assembly.
Can anyone tell about this?
Thanks in advance!

No idea, but looking at the datasheet: https://datasheet.lcsc.com/lcsc/18111411...C55679.pdf

I would have a guess that it's an exposed pad/connector for one of the RJ45 data lines. Perhaps they are suggesting to assume that the connector itself can introduce up to 100 ohms of resistance.

In terms of wiring, the + and - data cables will always be together as they'll be a twisted pair, part of the interference mitigation strategy.

Thank you, barray!

They are possibly 'narratives' or 'diagrams', I see! 
If then, they don't need to be mounted.

That's a very good guess ... we used to use it in the micro electronics world to represent a bond pad for an ultra sonic wire bond.
