Hello all,
Anybody knows what the two marked possibly 0201 20k precision resistors really are?
Sadly these two (refer to the photo) got knocked off because a physical mistake (the metal shield had to be wiggled to remove because of a broken screw, and lifting these to up in the end), and one of them got lost. You can see the identical smds below the marked region, a few more doublets. The one I have off board measured to be a precision 20k resistor but I cannot make 100 % whether the lost one is also the same. I cannot risk de-soldering the below ones either. Since there is no schematic, I thought of going with my gut, ordering 20k precision 0201 resistors, simply soldering back in, and repeat oh measurements on the spot for both resistors and compare them with the ones below... My idea is that these are identical resistors, possibly dividing the supply voltage to two, to be used as a reference voltage e.g. for a DAC or sth.
Does that sound logical to you? Any suggestions are welcome, thanks a lot.
