SMT Electrolytic Capacitor with no Voltage Rating

hbx

Sorry I am not finding any info on the green one and we do not have any SMT can with 4 terminals to offer , as for the other cap here is a link for 1000uf and I believe they are 6V we have 6.3V options to offer . https://www.digikey.com/en/products/filter/aluminum-electrolytic-capacitors/58?s=N4IgjCBcoGwJxVAYygMwIYBsDOBTANCAPZQDaIALAAxwDMdIAuoQA4AuUIAymwE4CWAOwDmIAL6EATFQoJoIFJAw4CxMuCqaABAFaAYk1YdIIAKqD%2BbAPKoAsrnTYArr1zipVAOxzkaLHkISSHIYADpaLQA1EEIYKMMQdk5zSxt7Rxc3CRAAWklEBSg%2BJ1Ug8gBWJmycn0LIYtL1CEYxbPzghXQWLTBNKidUKqA

Closer inspection may reveal that the capacitor itself is not a 4-terminal device, but that the placement thereof was designed to allow population of devices having different footprints.

Hello,
can you help me to find out suitable replacement for this one capacitor?
On top there is a marking like:
4e/4l->4 handwritten letter L or E
100

Thanks in advance!

Hello Gitsov,
Welcome to our community.
I am suppespecting that it is a Rubycon cap
Here is an example datasheet

It should be 10 uf and 10V

Hi wonderful people. I have a MS-6315 P3 motherboard with very tiny Aluminium electrolytic capacitors. I’ve made an attempt to identify them from what ive learned here so far. They might be

Aluminium Electrolytic
G = Series
10 uF
16 = Volt
104 Date code 2001 April?

Please help to confirm or correct if i am wrong. Thank you

Welcome to the forum.

10uF, 16V is my thought as well.

2001 is possible but seems unlikely given the apparent size of the components and density of the PCB.

I’d look for a four digit EIA standard date code (year/week YYWW) on a larger IC and then you can safely assume the capacitor was made within about +/-6 months of that date.

Hello, I found these capacitors on bag with other components that I bought from ebay. I beleive it is 4.9Volt (560uF - Also I measured it)… but the voltage is too low I beleive, so I want your opinion if I am right.

I’d guess it’s a 560uF 4V capacitor.

Couldn’t find any 4V 560u caps @ DigiKey so here’s a search giving all the 560u 6.3V parts. See if any of them will fit in the space available for the original 4V part.

Hello @oktabitt ,
Cornell Dubilier has a poly cap that is 4V 560uF option in their ULR series part number 567ULR4R0MEF-ND The markings seem to line up but the color indicates that may not be the exact part you have. We do however have a number of poly caps at 4V 560UF so I think those specs are correct for the part you have.

Can DigiKey or anybody supply a few capacitors as in the attached image?

I’m not sure of the value unfortunately, if somebody could assist me in this regard I would be very grateful.

Thank you.

Hello,
Welcome to the Digikey tech forum. Looks like you have a Nichicon capacitor, 10uf rated at 160v similar to this one, 493-9973-1-ND. This part is currently out of stock, closest options we have available are these capacitors which have a higher voltage rating, you will need to verify the dimensions to be sure one of these will fit.

Thank you Steve, the size is 8mm in diameter and 10 mm long. Does DigiKey have anything that would work? These are for Industrial grade routers so we need the best available components.
Regards
Alan

The closest I can find is part number 493-6705-1-ND. This would be 8x11. It is also 250 volts. We only have three in stock at this time.

Thanks Verna…I have put these in my basket. Where can I go to identify a specific LED that mounts on a PCB?
Thanks
Alan

Would love some help identifying this capacitor please. I think its a 33uf 16v. But im probably wrong hah.

Welcome to the forum.

I can’t, but somebody else on the forum may be able to identify it from the J8 & 2H codes.

From my perspective I expect it to be a 300uF electrolytic.

I would estimate the voltage rating based on the physical size and/or reverse engineering the circuits power supplies.

Electrolytics are made in many physical size configurations and different footprint configurations. So physical measurements would definitely be needed if the codes can’t be deciphered.

Hello,
Welcome to the Digikey tech forum. Looks like a 330 uf capacitor but I’m not able to find an explanation on the J8 or 2H markings. How did you determine this is a 16v? Do you have any more information on the part. Also does this have two leads coming out the bottom?

Its about 5mmx5mm. Like 1/4 inch or less. Its tiny. It was corroded off of an hp motherboard.

Also the 330uf caps that i have are huge compared to it. I only have a 330uf 16v cap in my little variety kit

I also get a 334.7 reading for uf on my digital multimeter
