Post help identifying capacitors here

[stevesg]

can anybody identify this 10U_0603_25V6M

10U_0603_25V6M
i need to know what to replace this with i assume it is 10uf and 0603 size, 25volt, but what does the 6m mean, is it 20% 10%
many thanks

So the markings 10V, 470 uF are all I need to worry about? All the other characters on there don't mean anything?

The "HC" marks indicate that these are Nichicon HC series - a low impedance type of capacitor. So you need to get the same type - i.e. match the impedance/ESR and ripple current to generally within +/-30%. The brands and series I listed in my previous post should all be close enough. So just look for, for example, Rubycon ZLH or ZLQ on Digikey, and you should be able to find good-matching replacements.

The cap that scottl31 posted above is Nichicon HC series, as lti correctly identified.
EB series from Panasonic is not quite adequate in that case, if ESR and ripple current capability are to be observed.

Relatively close replacements would be United Chemicon KZE and KZH or Rubycon ZLH or ZLQ. All of these are readily available on both Mouser and Dikigey ATM. Just match the capacitance and the voltage (10V, 470 uF), along with the diameter. Height-wise, UCC KZH and Rubycon ZLH and ZLQ will likely both be shorter, since they are newer miniaturized series.

*edit*
Forgot to add... Nichicon HW and HV series would also be close enough (if not better), along with Panasonic FR and FS. These are also readily available on Digikey and Mouser.

Happy hunting!

Tranks!

Hi, first time I see I cap like this, I suspect it is anyway as it is marked as C124 on the PCB. The markings means 0.1uF, 400V?

Well the in circuit ESR shows around 88ohms, I suspect something is not right...

Mine are through hole with two legs. This one you mention at digikey looks like it's not through hole. Is this right?

Then just fit a regular through hole capacitor like

EEU-EB1A471

just watch the leg spacing, diameter and height.

[scottl31]

470uF, 10V

go for something 105c rated 470 uF 10V or 16V, at least 5000hrs rated.. Like

EEE-FK1A471GV

on Digikey.

That looks like Nichicon HC series. That's a through-hole series, but I don't see a plastic base or surface mount pads in your picture. For a while, Nichicon marked some of their through-hole series like that.

[CapLeaker]

I don't know how to read the markings. Are you saying that either of those companies might have pictures on their site I can match this to? Thanks!

Mouser or DigiKey. But you can use just regular through hole capacitors too. You just bend the legs outwards.

Hello,
Would anyone know where I could purchase a capacitor like this in the picture?
Thanks,
Scott

Those one, please. Thanks

Hi could you please help me identify the capacitors arround bios chips

[DRKNSIDE]

looking for identity and where i can locate one of these capacitors shows 20K 560J E13 or E73 can really tell, Thanks!

Yes, Marcon (''N'') which is a diminutive of Marconi (in honor of Guglielmo Marconi, I suppose) and these are very old capacitors available in stores here in Italy in the era mentioned by PeteS in CA. They are still available as N.O.S. on some shops.

I also reinforce that, given their era, this is not a polymer. I would replace it with a Panasonic FC but also Nichicon PM would be perfect (E.S.R. not too low and capable of handling high frequencies). I would derate and use a 10V replacement.


EDIT: I confirm, electrolytic. As per specifictions in the inventory of a shop which sells N.O.S. parts. Picture attached.

Thanks Hitto & PeteS in CA!
I'll be ordering some nice electrolytics as replacements.

Does anybody have any old Marcom data books or data sheets to confirm it's a polymer or what the CFM series was?

My bad, these are made by Marcon, ending with an "n". Marcon Electronics, a former subsidiary of Toshiba Corp, then bought up by United Chemi-Con.

Given the age, if it is an electrolytic I'd suggest Nichicon PS, PM, PJ, or PW series, in that order of preference, whatever fits. I'm not sure whether polymer caps were coming into use in 1996.

Thanks PeteS, that's what my friends in the SGI collector community have done. Then again, some have failed to repair their PSUs or had them fail after a recap. Most of us are flying "flying blind" tho as SGI never released any schematics.

My PSU is working but outputting high ripple. It's very noticeable and was getting worse the more I used my machine, so I took it apart to fix the supply.
This is the only one of three like it in the supply that tested bad with my LCR meter. The other caps in the PSU were getting old but in OK condition and within tolerances.

Does anybody have any old Marcom data books or data sheets to confirm it's a polymer or what the CFM series was? I'd feel better replacing these three with a FP high ripple tolerant and super low ESR variant if that's what these are.
