i wanna know what the parameter i must to check before i replace the cap
i see 6.3 V AND 1500 uF
there are some additional data that i need to know?

Re: parameter about the Caps
Other than the voltage and capacitance rating, you also want to make sure the replacements are low-ESR and 105* temp rated. for most values, you should be able to find the exact diameter with a little hunting.Last edited by Topcat; 11-26-2005, 04:36 AM.<--- Badcaps.net Founder

Re: parameter about the Caps
the diameter is matter?
the size of the caps.
and i need exactly the same parmeters or something around.
10x alot.Comment

Re: parameter about the Caps
Diameter does matter - if it's too big, it won't fit. But if there's enough space on the board, you can use larger caps, of course.Comment

Re: parameter about the Caps
style,
I recommend that you figure out what company manufactured the part and what series it is. Then do a Google or Yahoo search for the company's website and find the series in the company's online catalog. If you have difficulty figuring out what company made it, post here what you find on the label - name, description of the company's logo - and someone here is sure to recognize it. Once you have the webpage for the series, find out what the case size, ESR, and ripple current rating is for that part - capacitance, voltage, and diameter (use a ruler - commonly used diameters are 8mm, 10mm, and 12.5mm).PeteS in CA

Re: parameter about the Caps
(Part 2)
Then find a similar part from a good manufacturer (there is a thread in the FAQ forum that provides links to good manufacturers' online catalogs). The favored brands here are Rubycon, Panasonic, United Chemicon (Nippon Chemicon), and Nichicon (except for the "HM" and "HN" series, due to a process problem in 2004). Try to match the case size, get equal or lower ESR, and get equal or higher ripple current rating. Since caps with OK ratings from a good manufacturer will be better than caps with "excellent" ratings from a poor quality manufacturer, choosing a low impedance part that fits from a good manufacturer should suffice.PeteS in CA

Re: parameter about the Caps
(Part 3)
Partial list of good brands and series:
Rubycon - ZL, YXH, and YXG (other posters may recommend other good series that I can't remember)
Panasonic - FM and FC
United Chemicon - KZE, LXZ, LXY, and LXV
Nichicon - HE and PW
Sorry for breaking this up in three parts, but for some reason it was the only way I could get this posted.PeteS in CA

Re: parameter about the Caps
ohh thank man
To measure the diameter i can use king of ruler.
i will try to find the model the u mention
but its difficult. i fint in IL store the folowing company:
nippon
LELON
SAMWHA
CHANG
MALLORY
u can plz rank them 1-best 5 bad.
thank u.Comment

Re: parameter about the Caps
1 - nippon

Re: parameter about the Caps
Quality-wise, the gap between Nippon Chemicon and Lelon is very large. I had a part from a current Lelon series and a part from a recently retired United Chemicon (a division of Nippon Chemicon) series (KMF) among a test group. The older technology UCC part fared far, far better under high ripple current. I suspect Samwha isn't much better. I don't know whether Mallory is manufacturing their own parts or re-branding.PeteS in CA

Re: parameter about the Caps
I'd say Nippon is good and the rest is crap.Comment

IIRC Mallory is a division of Cornell Dubilier, how are CDE's products?Comment

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

Hello!
I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.
The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.
I have studied the board and... -
I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,... -
Good evening
I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?
But I was also suprised about the bigger boys, which are 330µF 25V.
Could it be they used 25V caps because they were cheaper / available at that time?...
