Identify this component on my GPU

CntrlAltDel · Apr 13, 2013

This component recently popped due to my PWM fan connector not being wired properly, can anyone identify what this is so that I can replace it after it burned out, the PWM controller stopped powering fans but the GPU works fine. This burnt point is directly below the PWM controller.

I have tried looking up my GPU on the internet and trying to identify it from a picture of the PCB of the GPU but I was unable to my gpu's manufacturer's PCB

That looks like a circuit breaker? If it "popped" then that's probably what it is...You can read more about them on Wikipedia, but basically if a circuit is overloaded, it fill "flip" (like in a house) or 'pop' in this case to prevent damage to the circuit/component.

SlitWeaver :

Thanks for your swift response. What actually happened was, it set alight for around 3 seconds, it didn't exactly pop.

SlitWeaver · Apr 13, 2013

CntrlAltDel :

Yeah, that's how "older" circuit breakers work[ed]. That little part between the two metal parts is actually a paper-like substance which is burned through when the circuit is overloaded. There are similar parts on my PlayStation 2 (dead and disassembled) power supply board...thing...if you'd like to see

Overclock dat bitch until the breakers start popping like bubble wrap!
yeah

Hard to say could be a type of fuse. Although the "L" suffix makes me thing it could also be a surface mount inductor.

Nasty damage though.

I agree with smeezekitty, although the part has a "LB" designation. Also, there may be damage to the pcb and/or traces, so that might need to be investigated. If the card is under warranty, you may want to consider RMA'ing it.

smeezekitty :

That's the word I was looking for! *facepalm* Thank you!

the one below also been hit check her .

scout_03 :

uhh...what?

CntrlAltDel · Apr 13, 2013

The closest response I got so far is that it might be an SMT - surfacemount resistor

animal · Apr 13, 2013

SMT means surface mount technology.....if it were a SMT resistor its designator would begin with an "R", but in this case the component begins with a "LB" designator, leading me to agree with smeezekitty that it was some sort of inductor (inductors use the "L" designator), also appears as if the tracing (traces) in that area may have been damaged.

the part mark c 909 is also having something on the left side i use the magnifier for the picture and see a crack in it.

CntrlAltDel · Apr 13, 2013

Does this mean that C909 is a different electronic component based on it's suffix?

scout_03 · Apr 13, 2013

it could be without the schematic diagram of the card it is hard to tel .

scout_03 · Apr 13, 2013

the c is for capacitor and the lb for inductor bridge http://www.electronicsandyou.com/electronic-components-parts/electronic_component_name_abbreviations.html

smeezekitty · Apr 14, 2013

Yeah the component underneath is a capacitor (probably ceramic)

CntrlAltDel · Apr 14, 2013

So it would make sense to say the LB one is a surface mount inductor and the C one is a surface mount capacitor?

CntrlAltDel · Apr 14, 2013

Is the "B" in "LB" of any importance?

smeezekitty · Apr 14, 2013

Probably but I am not 100% sure what. Do you have an ohm meter?

scout_03 · Apr 14, 2013

this for the lb description http://wiki.answers.com/Q/What_does_LB_LL_LR_in_electrical_language_mean
