Hello all.
My P3 Standard had a crashed because of a faulty (shorted) capacitor.
Does anyone now the right value for the capacitor next to the mosfet, marked in yellow in the picure.

Thanks

I'd look at the other three motor esc to see if it could be identified.  Bound to be the same.

Do you can identify the capacity of the original capacitors in Micro or Nano farad ? You can ask a DJI hardware engineer for.

If you have a multimeter with capacitance testing then just measure the other 2 capacitors in that image i believe they are the same
The 2 either side of the M2 mark

Capacitors on this never short they open I suspect you're using your meter incorrectly in your forward biasing a parallel diode reverse the leads and see if you get a different reading I'd look elsewhere for my problem

Thanks to all for your replies.
I measured a other capacitor and it gave me ~500 uF. D'oh. They are all in parallel. So I had to desolder a working capacitor (a step I would like to avoid) and measured 4.7 uF.
For everyone who is interested, I used my FLIR camera and made short video of the shorted capacitor when applying 15.2 volts.

Forgot to mention, that the other part is a AO6500 N-Channel mosfet. After removing the faulty capacitor it doesn't heat up anymore.
