Hi,
I am trying to reverse engineer a PCB and it has a few of these parts labelled as capacitors. I am a complete noob and i have never seen capacitors like this. The picture is not very good but they are green with something like a circle in the middle and look more like LEDs or diodes.
I have spent quite some time in google but i have not find anything similar. The closest are SMD film capacitors, but the ones i have seen always have a line pattern, not this circular inner shape.
My multimeter can measure down to at least 100 nF without problem but doesn't see these ones, they must have a very low capacitance.
They are part of a 5V to 1.8V circuit within the board, something like this:
the capacitor in question is the one with the question mark.
