Hi,
I've always been wondering if there's a word for components on a PCB that are not mounted on purpose. For example, I often add footprints for capacitors in op-amp designs, just in case i'll need them if the thing oscillates. In the schematic I typically use the symbol of a crossed-out capacitor. Same for resistors. I saw this practice in quite a few other designs, and I think some of you did too.
Since I'm not a native English speaker, I wonder if those have a name? In German some people jokingly call them "anxiety resistors/capacitors", because one is anxious that the design might not work without them.
I read the term "depop" in reference schematics from Hittite, but a few minutes of googling tells me that this doesn't seem to be a wide-spread term. Except for depop circuitry in audio applications, which is a completely different thing.
Best regards,
GooGooCluster
