I have a RPi zero w that is missing a SMT component. 
Does anyone knows what component is it and knows it specifications so I can try to solder it again?

a schematic diagram is available on the web, pleasr use it– jsotolaCommented Nov 17, 2020 at 1:56

1@jsotola: It's a partial schematic. That means it's incomplete.– SeamusCommented Nov 18, 2020 at 16:38

It's a capacitor. I can't easily find the precise value on line. FWIW, an in-circuit test (probably inaccurate) shows ~80ufd for that part. The part also appears to be (physically) exactly the same as the capacitor just to its right in your picture.

82u (the closest standard value) is a huge capacitance value.– SeamusCommented Nov 18, 2020 at 16:49

It's an 0805 package and you can easily get them up to 100ufd at 6.3 volts. The value may be 47ufd in parallel with the adjacent one- I'm not sure.– BobTCommented Nov 18, 2020 at 17:55

1You may be right - I looked at mine, but saw no markings at all. If it's in that range (~80uF), then it's likely used for energy storage - not for a timer or a filter. And if that's the case, a wide range of values would work.– SeamusCommented Nov 18, 2020 at 19:49
