LF = possibly Nichicon LF series, if it has a blue text and mark for the negative stripe, though might be easier to reveal with a picture.

If I'm not mistaken, C = 16V rating.

Those are bipolar, too.

Re: Post help identifying capacitors here

Hello,

I've got an Asus X99 Deluxe for years, and few days ago, the PC won't start at all (no BIOS, no fans spinning, ...), only the "Start" and "Reset" buttons on the MB are lit. When I push the "BIOS flashback" green button, the NZXT Kraken, watercooling the CPU is lit while I push the button.

What I noticed is that the two bottom PCI-e ports, and particularly the capcitor between these two ports is burning hot.

I want to replace it to try to save the motherboard, with not much hope, but I'll try anyway

Could you help me identify the 2 capacitors, and, if possible, the two other elements circled in red, please?

What I can read from the bigger capacitor is:

FP 10K
48Cz
271
16

And from the smaller:

FP10K
46*z
561
6.3

(* is for character that I cannot read)

The other two elements, from top to bottom:

2R2
434
5OR

And

BA5P03
BCD1638



Second photo which is clearer for the bigger capcitor and the component just next to it:



Would these capacitors be ok to replace the two on my MB?
-
Nichicon RHA0J561MCN1GS
-
Nichicon PCX1D271MCL1GS

I'm not sure about the 20% tolerance. Is this acceptable or should I find a reference with a lesser tolerance?

Also, I noticed that on the back of the MB, a MLCC was not properly soldered (only one side was soldered, the other one was not). Do you know the specs of these MLCC? Nothing is written on it, and apparently, a myriad of MLCC exist, so I'm lost.

Thank you for your help.

From its marking it's a positive regulator anyway (the "P") , and most probably , 5volts for the "5" , And 3volts for the "03" ..
I'll keep looking for it more .

(MLCC) : Please show its picture , to know if it's ceramic or propylene or else , etc..

Re: Post help identifying capacitors here

Hello,

Thank you very much to both of you.

Here is the component on the back of the socket:



I removed it to be sure that it being desoldered would not damage anything else.

The unidentified component seems to be 3mm * 6mm. It's a bit tricky to measure, because it's between two PCI-e ports and the two capacitors, but I think this is the right measurement.

That's a smd ceramic capacitor , basically to provide power and stability to the CPU . Measure any surrounding capacitor , they're basically the same here .

For the BA5P03 , I need more , including height and even the pins ..

Re: Post help identifying capacitors here

Hello!

Can anyone tell me what these are and where to buy replacements?

Marked 1510A and 1310A

I have Google searched but haven't had any luck locating any info.

Thanks in advance

[Per Hansson]

Re: Post help identifying capacitors here

Looks like inductors, no need to replace.

[jiroy]

Re: Post help identifying capacitors here

Those are discrete Through hole ferrite shielded radial choke inductors , and like Per Hansson mentioned , no need to replace , and they look super fine .
About the marking , 1310A stand for 13mm x 10mm , A for tolerance 5% , and 1510A stand for 15 mm x 10 mm , A for tolerance 5% .
Without labeling them with their inductance values , like mh inductance , makes them standard from any series from some unknown company . So the only way to know their real value , without a schema is to measure one of them . Next , you can have any similar 1310A , meaning 13x10,5% , from any other manufacturer , like this series attached , SRC1013 .

Thanks Per Hansson and jiroy!

I thought maybe they were inductors but I wasn't positive. I have one that is discolored, so much so that the marking is almost unreadable, and the ferrite "cap" has popped off so I'm pretty sure it needs to be replaced. I attached the above pic because the markings were clear. These are in a Samsung surround sound amp/cd changer. I'll order a few and replace the one that's lost its head and see what happens

Thanks again!

Re: Post help identifying capacitors here

I have a motherboard MSI B350M Gaming Pro with missing components. One of it is a capacitor named in the schematic as "C560p50X4".
I need help identifying it as I am trying to find a replacement from an old board Asrock G14C-S.
The pads where it is missing are around 1.5mm apart so it should be really small.
It would be helpful to know how i could use a multi meter to find one from the donor board.

Hi guys!
Can some one to identify this type of smd capacitors from Gigabyte motherboard?

It's a smd capactor 560 picofarads or 0.56 nanofarads , 50 volts . Better test capacitors outside the donor board . Try find similar size and test it .

Re: Post help identifying capacitors here

Hi guys!
Can some one to identify this type of smd capacitors from Gigabyte motherboard?

That's a standard and very common capacitor smd 330 microfarads , 50 or 63 volts .. You can find it in any donor board .
