I think i am on to something.
I bought a dell sx-280, cost me like 2$ USD.
It has six panasonic caps labeld as
2200uF 6.3v +105c FJ (one of them is bulged but the others seem to be fine)
and also these Nichicon caps next to the processor
1800uF 6.3v HN(M) 105c A0507 ( these are like 10 on the board, all seems good and shiny)
from the underside of the popped fz caps i can see two holes so i can fit a thinner one there two.
so what will u guys suggest from these ones ?
the panasonic are same size as old one but a bit taller.
the nichicon are thinner and same height as the panasonic.
as i have read in the forum that we can go over uF range a bit
is 2200uF too much or safe? Both caps on the boards legit, if u guys want i will post pics of them.
Thanks again all you u guys, i had alot of info gained from you guys. thanks for helping the noob
also forgot to tell abt the new caps, i got them from local shop, he said that these ones are motherboard sized, he didnt knew if they were good quality or not, just said that we get these ones for motherboards.
Those will work as well. Be careful of HN though. Some were prone to failure, but it was supposedly corrected by 2005. Those are week 7 of 2005, so they should be okay. If they came out of a small form factor Dell, I'd be extra cautious. The small form factor computers are known for overheating caps.
so can i use all the caps which i listed for dell pc ?
as some have more uf and some have more volts, which one of the above will be good ones. also the dell had these caps bulged, i have solderd them out.
1. panasonic 2200uf 6.3v fj series
2. nichicon 820uF 6.3v HM(M)
3. 25v22 ZA [R] A 0441 ( so i guess its 22uf 25v ?)
The HNs you listed earlier are the only suitable candidate from the Dell. You can very capacitance a little if you absolutely have to, but you want to stay within 20% of the original values.
I'd still go with the Panasonic FL you had a few posts back. Panasonic caps are top quality, and those have been by far the best replacement mentioned the whole thread. Given that you have access to the correct replacement, I would say use the FL as they will definitely get the job done. It seems sort of silly to experiment with different sizes and values when you have the correct replacements available.
I agree. The Panasonic FLs are the best for those two blown caps.
I looked at the pic of the two Sacons is a sea of solids. Very interesting.
In other news, my desk is bloody and I seem to be bleeding from my forehead.
I still think the New FL panasoinc i have are fake, so am trying to get something from used parts which will have at least 2nd class parts. As here the new parts we get are like 3rd grade fakes from china.
so is thes "1500uF 16v HN(M) 105c H0507" good enough, i mean the voltage difference 16v ? i thinks the voltage is like 30% more, can i still use it ?
also i have old MSI GeForce 4200ti, it has some smt caps, solid i think but i cant ident them as they use some differnt codes. i will try to get its pic and post it as it might have some good quality parts, as this one was the very best card i had in old days. still kept it as i have used it alot, maybe it comes in handy and i get good quality parts from it.
The panny FL new ones i can get like 12 for under 1USD, i guess they are fakes or the person who got them here got them in huge quantity.
I am convinced too that FL are real, i went to the shop again and asked him in the box that they came in, he didnt had box of those but shown me a big box of nishicon's i think it contains like 1000caps, they order in quantity.
before i put them on, i need to know one more thing, can u guys tell me the datata sheet of these solid cap's
silver solid cap with purple stripe
647
SEPC
560
4
so i cant use these sepc cap's for my card as they are 560uF 4V, i thought they were some kind of code. Thanks again, i will recap my card and will let u guys know. will recap it in 2 or 3 days.
Thanks to all you of you. I got really good advise from u and gained a bit of knowledge abt caps.
still have not recapped my card, as i needed practice to recap. As an experiment i have replaced the 3 caps on sx-280 with smthng cheap, as to my surprise the board is alive now, before it only gave amber light. now it post and i can go to bios. i will practices a big more before i recap the video card. and am still keeping in eye on used parts to find solid polymer caps
I also had problem with 2x Sacon FZ series 1500/6.3V on ATi X550 and need some recommendation about the replacement.
Did you guys talking about these Sacon FZ series?
1500/6.3V, size 10x12.5mm.
Ripple Current 1800mA rms.@100KHz 105c
Z 0.022ohm@100KHz
If correct, My question is... Can I used these Nichicon HZ series as replacement.
1000/10V, size 10x16mm.
Ripple Current 2960mA rms.@100KHz 105c
Z 0.010ohm@100KHz

You can use Nichicon HZ but Panasonic FM or better are good enough to replace Sacon FZ.
It's not common but in -some- circuits [**] taking ESR too low can cause problems so personally I would not replace FZ with anything better [lower ESR] than MBZ, WG, FM, FL, FJ or HM.
- But that's just me..
[**] Never seen it apply when caps are just being filters, but, in control circuits the volt drops across caps and their charge times are sometimes used as time delays or for dynamic biasing to turn IC functions on-off or establish set-points [trip points].
ESR can affect that volt drop and/or charge/discharge time.
So, if you KNOW the FZ is just a filter cap [and an FZ probably is] then and HZ should be fine.
Personally when I want ESR as low as HZ I'd use a polymer if at all possible because the 'extreme' lytics like HZ I suspect have more heat issues like KZG and KZJ. - Can't 'go poly' for some voltage/uF value though...
