I recently learned about Kyocera Q-Bridge parts. Those are infinity-ohm-resistors, but conduct heat reasonably well. Similar parts are also available from other Manufacturers.
We don't have them in #KiCad yet, as a first step I want to add a symbol. The hard part is, that this is new, so IEC60617 is no help at all.
And I could not find examples in the datasheet.
And its not clear which reference-designator to use.

So what should the reference designator be?

@cccpresser I should check what symbol our parts department at work gave for these, after I put in the provision for these in a product. My vague recollection is that it was a resistor with a Sigma symbol?

@cccpresser I've used plain old resistors for this too (10MOhm) not as good as the dedicated AlN thermal jumpers, but still 10x as good as 1.6mm of FR4 and much cheaper than dedicated thermal jumpers.
