I desperately need to know the component and the value of this unit so I can replace it in a OnePlus 7 Pro mainboard.
1) Any idea?
I suspect that it might very well be either a 2.2 uF capacitor, or a 1 uF. It is connected to the VDD N-FET pin of a Samsung UFS.
So, I think that it is a Samsung UFS V_DD N-FET pin 0201-sized grounding ‘MultiLayer Ceramic Capacitor’ (MLCC).
2) What would happen if I installed the 1 uF while a 2.2 uF capacitor was required, or vice versa?
Thank you so much in advance!
I have not been able to find a OnePlus 7 Pro schematic, but have found one of the OnePlus 8 Pro with a Samsung KLUDG4UHDB-B2D1 UFS-3.0 (listing a 2.2uF); Oneplus-6 UFS 2.1 (listing a 1 uF but in parallel), which is most probably Samsung’s KLUDG4U1EA-B0C1 which the OnePlus-6T has which is also UFS-2.1, OnePlus-6 has UFS 2.1 2-LANE 64 GB / 128 GB / 256 GB editions, while OnePlus-6T has 128GB / 256GB editions, and there is only a half year release date difference ; and a OnePlus-3T with Samsung’s KLUCG4J1CB-B0B1 UFS-2.0 (stating that a 1 uF one should be used in case of a Samsung UFS). The OnePlus 7 Pro has a Samsung KLUEG8UHDB-C2D1 UFS-3.0. This makes me to conclude that it is most probably a 2.2 uF. I have added attachments of the schematic diagrams I could find. I have highlighted the V_DD I_Q line.
Any thoughts on this?
