Hello, do you know what is this component pls of Nikon D800 camera shutter?

[corrize]

It is on « board » of Nikon D800 camera shutter, probably for command electro magnet (the green stuff). The chip is marking G11 and have a polarity mark, so maybe dual diode ?
The chip is good, the goal is I can deduce the value of the capacitor missing above.

Chip can be FMG11A Dual N transistors
if so, capacitor may be 0.1uf - 1uf

Update : I tested with 10uF cap (not found closest value in my stock) and the shutter works. The first curtain moved (before nothing was appening).
But the first curtain stayed stuck, so I was doubt on mechanical issue.
I have another D800 with shutter working fine (but another issue), I disassembled and checked, and found a difference of behaviour. I found a little metal part with no spring reaction (on all curtain's positions) compared with the good shutter (it has permanent spring reaction). So shutter need to be replaced.
I tryed to measure the capacitor onboard and found no value, probably out of range of my cheap meter.
If the shutter hadn't had a mechanical problem, I would have replaced it with a 1uF capacitor.
Thanks for help.

I would replace the capacitor anyway and see if the motor runs just for the fun of but that is just me

I did it, But the motor is not on the shutter. It turn. The little electronic seems control two electro magnet (green stuff) for stopers.
At the first test, I said ; "nothing happen" but in fact the motor turned but curtain did not move. It was stucked.
