Re: badcaps in a ATX PSU

i see what you mean, closest i can see is panasonic FK 2700uf

can you give me a link?

Re: badcaps in a ATX PSU

Digi-Key doesn't carry that part. Their FK stock is fairly limited. And Digi-Key doesn't have any 2700mfd 10V parts in d10mm. I think Wester is right...I would just use 6.3V caps, but that's just me

Re: badcaps in a ATX PSU

ok i will stick to the caps i have

i looked and it seems that it's a bit cheaper on shipping

Re: badcaps in a ATX PSU

i found this
http://www.mouser.com/Search/Product...YB100E272MJ30S

it's a chemi-con KYB 2700uf 10v

Re: badcaps in a ATX PSU

Oh very nice. Will they do free shipping? Otherwise it's not worth splitting your order unless you want to move them all over to Mouser.

Re: badcaps in a ATX PSU

the interesting thing is this:
if the pro's like panasonic & rubycon etc cant make a reliable 3300uf cap in a 10mm can,
then obviously the crap company's cant either - so i wonder how good the original part ever was?!!

the old one looks to be in good shape

Re: badcaps in a ATX PSU

in what way?
do you have an ESR meter and a way to check ripple current?

i do have a ESR meter but i don't have a way to check the ripple current of the caps

What, you mean all those thousands of 3300uF 6.3V UCC KZG... that were erupting like volcanoes?

In all seriousness, I think Rubycon and Panasonic came close enough to pulling it of with the 3300uF 6.3V MBZ, MCZ, ZLJ, FJ, FK, and FR. And Nichicon with 3300uF 6.3V HW, post-2005 HM/HN/HZ, and UCC with 3300uF 6.3V KZN (all 10x25mm except for FK which is 10x30mm). I think 3300uF 6.3V 10mm Sanyo (Suncon) WG were reliable as well. But most of those series are too low impedance for anything but modern PSUs designed for lower impedance caps.

don't ask me how

Re: badcaps in a ATX PSU

i may desoder the 3300uf canicon cap and take a closer look at it

Re: badcaps in a ATX PSU

dont desolder too much without making notes - we dont want you coming back and asking where each cap goes!!
