^^The title says it all. What brand do you vote as the worst? I'd say probably GSC/Sacon, since they're the only brand I see fail after only 3 months use. I'm not going to bother doing a poll here, because there are more brands than available poll options.

Re: What's the worst brand of capacitor
UCC KGZ. At least with most other bad brands they bloat when they die and you can easily tell which ones to replaceCap Datasheet Depot: http://www.paullinebarger.net/DS/

Re: What's the worst brand of capacitor
If we're going by what I've seen bloated/failed on a regular basis....we can say Rubycon, Panasonic, Nichicon, Sanyo, Samxon, UCC.....I've seen them all. Ohh wait, you're wondering about the REALLY crappy ones...
FWIW, the high-end brands I've only seen fail due to overheating....mainly in Dell and HP toasterboxes & iMacs.<--- Badcaps.net Founder

Re: What's the worst brand of capacitor
this is a moving target.right now capxon in hdtv's and monitors.then samxon.while some of theirs are on the "aceptable" list they have some series that are always failed when you see them.like gf.Comment

Re: What's the worst brand of capacitor
Fuhjyyu, Rulycon, GSC, Jamicon, CapXon, Just to name a few.
PSU, I would say Fuhjyyu. Rulycon are just as bad though.
M/B, I would say GSC. OST, Teapo, KZG, are just as bad.Comment

Re: What's the worst brand of capacitor
Is an "Elite" polymer more reliable than it's electrolytic equivalent? If companies more to more polymer caps we might see new brands to go on the list.

Re: What's the worst brand of capacitor
I'm not liking these new "Enesol" polymer capacitors...
I'm seeing them being used quite often in PSUs and in "all polymer" motherboards...
The caps very often have insufficient markings, so there's no way to know what values it has, and they don't seem as reliable as more recognizable polymers....
I'd even prefer Capxon polymers... I think the Capxon polymers are good... They're just now being introduced in lower-end motherboards.Comment

Re: What's the worst brand of capacitor
That's quite interesting mockigbird because i've seen Elite and Capxon polymers but not Enesol. What's the brand on the top like?
Not seen one fail yet. Not sure if it's possible to make a "bad" polymer.Comment

Re: What's the worst brand of capacitor
For example, the new Platinax 600W Review at hardwaresecrets:
And on the new TX550M that seems to be making its rounds among the review sites:
Values are there, but there is no way to determine the series. PCBONEZ has tried... In their catalogue, they do show markings on their caps that have to correlate, since it is in the catalogue, but as you can see, the ones they ship have no series printed on them...Comment

Re: What's the worst brand of capacitor
That's worrying if they have poor reliability. Do you know of any reported failures as of yet?Comment

Re: What's the worst brand of capacitor
My two cents: GSC/Evercon/Sacon/etc. Absolutely horrible.
I've never seen a single bad Hitano, incidentally.
In fairness, every good brand seems to have its share of off-days and misfires. I've had to replace more Chemicon KZG's than I'd like to (including two that just evaded my notice earlier today), and I am still trying to come to terms with Rubycon MCZ's occasional intolerance of heat. (Must be a trait common to the ultra-low Z lytics?)
It gets real annoying when certain series are known for failing without any obvious outward signs. Lacking the right tools for the job (if I had the money to afford a good ESR meter I wouldn't do this!), my method for testing rows of suspect capacitors is rather simplistic and crude: pick one of the row, cut it with a pair of pliers or metal cutters, and seeing if it hisses, and/or leaks or spits fluid. Once I cut a non-bulged Nichicon HN(M) that viciously spat little blobs of electrolyte - it was definitely under some serious pressure inside.The ever-amazing (and ever-affordable) KY, Chemi-con's best kept secret.
I'll probably be the only person going to SteamOS once it gets out of beta (ha ha.)Comment

Re: What's the worst brand of capacitor
It is. Most polys actually have a wet polymer electrolyte and are essentially a hybrid cap. If the manufacturer leaves out that chemical that prevents electrolysys (which was what caused the plague with electrolytics), the poly will eventually fail, but without a vent stamp, the can will go into orbit. AFIK, the only true solid polys are chemi-con PS_ and Nichicon L_I love putting bad caps and flat batteries in fire and watching them explode!!

Re: What's the worst brand of capacitor
MCZ isn't sensitive to heat... MCZ is sensitive to INSANE levels of heat combined with unreasonable amounts of ripple... When you combine these two factors in an older computer - firstly, that the power supply's capacitors are no longer filtering enough ripple and are thusly passing them to the motherboard's capacitors, and that older computers can be dusty and poorly ventilated, MCZs preform extraordinarily well whereas cheaper capacitors fail much quicker...
Just look at the old Xbox 360s... Rubycon MFZ.... There are 4 near the CPU, these never fail (Unless people "fix" their xbox by baking it in an oven - and even this can be done successfully, if the caps are insulated from the heat). The Nichicon HNs do well in there too.
What about Sanyo OSCON? And also the SEP and SEPC series?the only true solid polys are chemi-con PS_ and Nichicon L_Comment

Hi people, I hope this is the correct spot to post this, I'm new to the forum.
I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.
I hope these photos make it clear which component I am referring to:
(yes, the soldering is a bit botched from removing the blown one, I know)
I have found the board schematic (attached), but there does not seem to be a boardview available. I have never... -
I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
I know that these capacitor will not last as long as nichicon capacitor... -
Want to repair some broken floppy disk drives. I need help to identify the brand of this capacitor to find a suitable replacement.
Did someone know the brand of the capacitor or a suitable replacement in terms of esr / ripple?... -
I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm
And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,... -
When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
