    Re: Are this caps something special?





    I am pretty sure the traces are fine. The solder points are a bit dirty but no leakes on the board. It helps that the caps hanging upside down on the board. I am also pretty sure there is no damage from soldering as I made sure i heat the pads as shortly as possible.

    I wil take a look at the Panasonic FT caps but dont think the higher endurance is necessary, the setup only have to work for a few years.

    Both thanks for the info ...

    Re: Are this caps something special?

    After 1 1/2 year this caps still haunts me.

    After replacing the caps with the tantalums caps did not fix the problem it even create a problem, i found that out just recently.

    After a year trying to fix this board we finally got a other board that worked. But this board has a lot of leaking/defective caps. So I replace 1/3 with tantalums and after that it wont boot, so i replace them again with caps that are not dead from a other donor board and the system boot again, but with a catch. We have to boot twice and I...

    Cant find the old or new model of the Panasonic CE Z Serie

    I want to replace the caps of my Sega Dreamcast power supply. But one of them is a 400v 47 CE Z. Some how I cant find that serie or the replacement for that serie.

    I am not sure if they really are Panasonic. They are all CE with FC and NHG and that are Panasonic models. But all caps are branded with M.

    Anyone can tell me what serie or replacement serie this is?

    I understand that, but that was not what I was asking I like to know if it could be a problem if i use tantalums, would it be a problem if the capacity are bigger that the normal caps that are on the board right now?

    I dont think it would, but want to be sure....

    Are this caps something special?

    I been repairing special mainboard for a exposure machine but after replacing a chip and some cleaning it seems not to boot correctly so seen the machine is about 25 years, I have replaced all the caps with cheap chinees caps because that was something i have in stock. But after that there was no life at al. Been probing with a oscilloscope but noting.

    So I been thinking, sure the cheap chinees caps are not the best but noting at all seems a bit strange. Are this something special?

    Yoda voice: Like no problem I do

    So would you take the same caps that @mockingbird posted or would you pick others?

    And do you think I still should replace some with Polymer caps? I have no experience replacing normal with polymer caps. So i have to go 100% on you all replying on my topic....

    Re: QDI mainboard with bad caps - Need some help


    Well the thing is, none of the creative sound cards have this connector. I think it is called a SB Link because of the many cards that are compatible with the Creative Sound Blaster cards.


    Yes but they use a special chip for this ISA. They stil use this kind of chips on boards with the latest sockets.


    Yea, it is nice if you have no other choice. But I guess that it is not that compatible as the real deal. Also it is not only that why I dont want a more modern board. Win9x has also no...

    Yes, we still talking polymers.



    What can symptoms can I aspect? Does it happen a lot are there specific boards that are known to not handel the polymers?



    Well I love to, but I have not found any board with a 865 and PC/PCI connectors. If you know one, I love to hear from you.



    Sure, but there are not new. So used polymers has lesser lifetime left than new ones and new polymers are not that expansive. Or better, not replacing...

    Re: QDI mainboard with bad caps - Need some help



    I can understand that. I have read that on other places to. But I read also that still higher caps are better.

    So I am a bit in conflict what to buy. Maybe 820@2.5 is adequate but about my earlier question, can it hurt to go say 2000@6.3 in your opinion?...

    Why could it not work? I don't mind buy new caps, This is not a board that only has to work for a few year. This board has to work for many many years to come, and that is because of your last 2 questions.

    PC/PCI is a 5 header connector is mainly made for sound cards. This connector is also known als soundblaster link or short SB-LINK. In the dos era games talk to the sound card in a different way than now. Games need a direct excess to the card and specifically the way that ISA cards work, PCI is not made...

    Re: QDI mainboard with bad caps - Need some help

    Ok I am getting a bit confused.

    I have now different answers for polymers:
    1. 2000uf
    2. 1500uf but he feels more comfortable with 1800uf or 2200uf with 4v or 6.3v
    3. 820uf and 2.5v

    You probably all are right, but this do not make it easier for me. Let me ask this: Can it hurt to have a high voltage and capacity caps? My guts say no, but my expertise is not enough to be sure.

    Re: QDI mainboard with bad caps - Need some help



    So what i understand is that with caps 3 I have no choice than to go with electrolytic? If so would going with the Rubycon ZLH in place of the ZL be a good option. Or a better question is will a higher lifetime also mean it takes longer before i have to replace them with light use? Or is it like a drivebelt in a car what ever come first? So like if i take 10000 hours caps, it is 10000 hour of use or 10 years after production what ever come first?

    Other thing is i see the same specs caps from Panasonic but...

    Thanks.

    I have some questions. What do you suggest go with polymer or electrolytic? Also what you didn't wrote is what I should do with the caps of number 3. Could you give me a suggestion?

    Some additional information:

    The diameter of number 1 and 2 is 10mm and number 3 is 13mm...

    Ok you say try, are there possible problems? Also if I replace them with polymer caps what should i buy? I found on Farnell 2000uf polymer caps only from Wurth and i just read that they are very unknown and what should i replace the 2 Rubycon caps with? I only found 2700uf not 3300. Also what about the ESR the Wurth has 3 kinds is ESR not important?...

    QDI mainboard with bad caps - Need some help

    Hai all, I need some help with this project.

    I got a mainboard that is in need of some recapping. I got it a week ago from Ebay with caps that look good, but after a week I got 3 leaking and 2 bulging caps. All the caps that are bad at the moment are the ‘Nichicon 6,3v 3300uf 105c H0249 HM(M)’ but next to it are ‘Nichicon 6,3v 3300uf 105c H0302 HM(M)’ and I have read that they are even as bad, but not showing it yet.

    Also I like to replace the 3 ‘Rubycon 16v 2200uf 105c S0245 ZL’ to be safe and 1 ‘HD Z1 1500 6,3v’ because...
