Can you help me to identify the Capacitor in the image. I need to buy a new one. Thank you very much
Dear all, after a long wait for the delivery I think the capacitor it too small.
I checked the diagram: it might be this one???
Bu iyi bir soru mu?

I'm doing a bit of poking and much like @oldturkey03 mentioned, the schematics for the 820-01061 are not available.
But there will be a lot of correlations with the 820-00597, which we do have schematics for.
Without burying my answer too far into this, I'm going to hazard that these are the same caps as the ones that are in proximity to the Macronix Flash memory controller MX25L6473F, also present on the the 00597. Which are 1µF 6.3 Volts in a 402 package.
If you want to deep dive on this, you can. The chip in question is actually the bootrom. Which is super important. Looking at the circuitry in the picture it's not actually connected to the chip. You can see two little vias on either side, which will lead to the other side of the board. You can try and follow them to try and confirm what part of the circuit this might belong to. Which might help to get more specific values. if you don't want to go based on my generalization.
But without doing all that work, I am still going to assume it's correlated. Even on the 00597 some bits go through to the other side of the board.

@flannelist awesome answer as always!
Great I can see is not connected to the chip. The Imac wont boot anymore. I might try to order the piece and solder back to the motherboard.
I have the schematic program but it is a Sanskrit for me.
Maybe you can have a look.
Thank you
Luigi
@luigicapaldi This is the same schematic I have, which is for the 820-00597, which isn't quite the same board. It's where I got the values for the capacitors I mentioned in my answer :)

@luigicapaldi taker another picture but this time Zoom out. We need to see where on the board this component is located. You logic board is a 820-00597or a 820-01061?

Thank you very much for quick reply. I managed to take some shots. Here the image.

@luigicapaldi nope. 0201 is half the size of the one you have.

ok I measured the one close to the lost one that from the original image looks the same. The size approx is 1 mm by 0,5 mm but my plastic meter to measure is not very accurate. Tomorrow I will get close and take a photo. Thank you
