I've got an older Asante FR1104G router cracked open as it's out of its warranty period. It was always flakey, even the ones sent back as in-warranty replacements. There are 16 identical 47uF 16v caps with a strange branding. They are black with white lettering and the brand logo is a lightening bolt with a stylized "SC" next to it. I've got some Nichicon HE's left for this project, but I was curious if anyone has come across this specific brand of capacitor before.

Re: Anyone ever seen these caps?
Alright, here it is. I scaled the photo size down but you should still be able to see it. I can't determine whether these caps are a known bad brand or not. The router works, but it will periodically lock up and stop routing packets.Attached FilesComment

Re: Anyone ever seen these caps?
I found these 'SC' caps inside my old wireless router. The router kept having problems and then finally stopped working altogether. Opening it up, I didn't see any bulged or vented caps, but I did see this 'SC' brand - and that the power diode was sparking when I applied power.
I was also surprised that it used a standard wireless PCMCIA card for the wi-fi services, connected to the external antenna! I've now replaced it with a new-model router (same manufacturer though), and it's still working today.You know there's something wrong when you open your PC and it has vented Rubycons...Comment

Re: Anyone ever seen these caps?
I think I have a positive ID on these. I ran across these caps today at work:
The wrapper color is different from Kacerdias's description but the logo sounds the same. Who are they? The source is Surge Components, who sells Lelon here in the US. So these are rebranded Lelon caps. Notice the use of a Nichicon series name, "PW". Also note the lack of any date code or factory code info. When I unwrapped a sample, I found (through a rudimentary test) that, despite the me-too use of a Nichicon non-aqueous series name, the electrolyte is aqueous. This was not the first time I'd found Lelon fudging or failing to control the electrolyte type.Emerald green wrapper
Logo – Single zigzag lightening bolt followed by a stylized “SC”
“330uF 16V”
“105C Vent”
Gold polarity stripe with inset arrow and “-“ symbols
“PW”
“L.E.S.R.”
No fate code or factory code
Bung has two concentric rings with slight clearance for cleaning around the leads; the wrapper, not the bung will be in contact with the PCB.

Re: Anyone ever seen these caps?
Well, that seals it. I'm recapping this router. Thanks for the replies!Comment

"fate code"? I promise, that was a Freudian Typo, however appropriate it may have been.PeteS in CA

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?...
