What resistors are these? (zxw)

I accidentally broke three resistors on the main motherboard of the device. And I want to solder the resistors independently.

I would be happy if someone who has the software zxw can find me the resistance level and the size of these resistors.

(By the way, so that more people can use this in the future, I will mention that two of them are on the sim way)

I marked the resistors here.

Thanks!

@haim1, What is the board number on your phone? I’ll see if I can dig up a schematic and boardview.

@geirandersen L 29 if you talk about that

Had a look at XZZ, since I tend to not use ZXW where schematics are concerned. Resistors in question are as follows:

R3003 (green) 47 ohms

R3001 (yellow) 100 ohms

R3006 (orange) 1K ohms

Hope that helps!

C2901 (red) schematic says 100n? Which i would interpret as nanofarads? That's sort of an atypical way to write that, I would have just said .1µF but that's beside the point.

R2902 (blue) 2K ohms

C2906 (purple) 33pF

Thanks you.

Just to be sure.... can you write me the size of the resistors?

And one more question... I search on googleans some websites "R3003" for example and i dont find this power of resist (47ohm). Why?

da

@haim1 R3003 is the components designation on this exact board, it’s value is 47 ohms. As for size (package), it’s most likely 0402

Thanks!!!!!!

@haim1 @geirandersen is correct about the designations. That's just how Huawei refers to the resistor in that location on that specific board. So they don't have to say the resistor fourth in from the left, or something like that.

As for size, the schematic doesn't specify. 0402 is quite large for a resistor, but they do look bigger than resistors on most iPhone boards, which is what I am most accustomed to (those are almost always 1005). So I would wager you're right. Either than or 0201.

da

@flannelist I almost wrote 1005 without even considering anything else, but I took a last look at the picture in the question and I realised the pads looked fairly huge. Now, they could very well be 0201, my eyes ain’t that good looking at a picture on then screen :P
