Broken off component

Go to solution Solved by mariushm,

The inductor is part of dc-dc regulator circuit, the controller chip is right there U852 ... get the part number off that and look up the datasheet, it will have some example circuits and see what inductors they recommend in the typical example circuits.

 

alternatively, measure the spacing between the pads ... based on picture and knowing that up911p in the left corner is 5x5 mm ,  that inductor footprint is 7-8 mm, so you can go on sites like digikey , mouser, newark/farnell and look at surface mount 6.5-9mm pitch inductors and pick one ... my guess is the rating is somewhere in the 4-10A range and sub 0.1 ohm

 

So some examples https://www.digikey.com/short/4cnwzv

Heya!

I got an free 1060 Zotac by a friend of mine. The 3Gb version though.

 

Sadly there is a broken off component on it. I could manage to find what it was through a video.

It is an inductor with 4.7uH, but i dont know which Amps will flow over it.

 

Is there a way to tell how big the inductor has to be or is there a "parts list"?

I have a pic attached to show which one it is. Its labeled as L20

 

Thanks

Kurt

Yes, it's the 4R7 - marking on it that tells you its value, ie. 4.7uH.

I found that value already, but i can found inductors ranging from 1 Amp to lik 50 Amp.
Thats what im not really sure of  😅

Yeah, I just noticed that. I was a tad hasty in replying and didn't fully read your post, sorry.

 

That said, no, there is no way of finding out any of its other specs just from pictures and there's about 99.99% chance you won't find official circuit-data anywhere, either.

All fine!
Happens to the best though.

 

So, i could maybe get one thats looks as close as possible or just go with 50 Amps and call it good 😄

Im thinking about E-Mailing the manufacturer, but i dont have much hope there.

 

Thanks

Measure the white square on the silkscreen and clearance to cooler if applicable, that will give you a standard package size. Then look up parts with the correct inductance of the right package size, and there won't be much choice anymore since that will basically constrain the current that can pass through it.

Mhh thats a good idea.

I will look into it and what mouser has in store for this size or other stores :D

Thank you!

Thank you very much!

This was something i didnt think about! :D

The inductor is used to create 1.2V with that chip at U852. The Datasheet shows max of 4,7A.
I will try to get one that can handle a bit more to be secure.

But now i got to source a new SMD Capacitor too. Seems like my friend broke more then just that inductor 😅

But your help was amazing. Thank you very much!
