capacitor value - help

[fddizon]

hi to all,

does anyone know the value of this tantalum capacitor?

NEa
JE8

thanks and regards to all

Use 330uf it should work.

u means replace with 330uf its should work? what bad value or bad symtom of this capacitor?

[mariushm]

No, don't replace with a 330uF without further explanations from other members.

Tantalum capacitors are not that high in capacity, usually they're not more than 22uF and are usually used because of low esr, so 330uF is too much capacity and depending on the voltage rating they may not be very low esr.

To me, those codes don't tell me anything, each digit might mean something in some standard or under the manufacturer's standard. But not knowing the manufacturer, it's hard to say.

Maybe if you post a picture of the area around this capacitor and say what hardware it is, someone can suggest some replacement.

I agree - Siddiq - can you explain how you decided on 330uf and what about voltage?

I have looked for the coding and so far failed to find anything so a picture would help

(max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.

Please do not post inline and offsite as they slow down the loading of pages.

hi,

thanks for the replies.
here is the picture

[mariushm]

and the circuit board with the location from where you removed it? Picture with that as well please.

Do you have a multimeter capable of measuring capacitance? If yes, try to measure it.

Maybe you need THE SMD CODE BOOK, i'll upload if you need it

OK In this PDF PAGE 2

www.ncc-matsuo.co.jp/pdf_e/251_o.pdf

Where it says "Marking" it suggests that

For a case type A or B ( The one with gA8 in it)

If that were to say jE8 then reading the notes it would be a 6.3v 150 UF

What does anyone else think?

[siddiq]

Sorry guys, I was a bit hasty there, the value is actually 150uF 6.3v. A faulty laptop came in some time back and i could not get same value so I replaced with 330uF (6.3v) and laptop worked fine. I've posted picture of a D600 motherboard.

Have many times to upload but keep " sending request to www.badcaps.net..." , here is direct link http://www.4shared.com/office/4bG73c..._CODE_BOOK.htm

NEC TOKIN conductive polymer tantalum capacitors
NE:NeoCapacitor a:Production date code
j:6.3V E8:150uf

[Evil Lurker]

Duncanbest beat me to it. Those are indeed neocapacitors... basically some weird hybrid tantalum polymer super low ESR caps... as best I can remember the ESR is so low that you would have to use Kelvin leads to measure their ESR properly
