The Hall of Shame - Badcaps Photo Montage

Re: The Hall of Shame - Badcaps Photo Montage

since this isnt the vip room...

Ah, that explains the g-rated analogies above, then.

Otherwise, I was expecting the jokes to be more about extra skin (or lack of) on certain... oh yeah, this isn't VIP/off-topic. NVM!

Re: The Hall of Shame - Badcaps Photo Montage

yea me three! i find sleeving errors very funny too. since this isnt the vip room, all i can say is that under-sleeving reminds me of women wearing shirts that are too short , exposing their abdomen or someone walking around in public in various states of undress.

over-sleeving reminds of someone wearing a fat suit or wearing clothes that are too big or too baggy for them. in short, over-sleeving and under-sleeving make very poor fashion choices for a fashionable capacitor or if u want to have a capacitor that looks fashionable, aesthetics wise.

The Ruby MFZ probably sat on the shelf too long without use, and they don't like that too much either (though nowhere near as sensitive as UCC KZG). I've also never seen MFZ in that size offering (680 uF @ 4V). Custom spec caps, I suppose?

As for the Samxon GF... meh, those are known garbage. Not surprised it failed.

The blue Samxon looks like GS series. Those are general purpose series... and also not very good, especially if there is any heat involved. Also, that sleeving error is very funny. I've seen caps over-sleeved or under-sleeved - even from the good Japanese brands, but nothing this bad, lol.

Re: The Hall of Shame - Badcaps Photo Montage

Some caps from a grab bag; a (brand new) Samxon GF 47uf 25v that is blown out the bottom. A Rubycon MFZ 680uf 4v cap that is bulging (tests at 230uf). and a Samxon cap with a heat shrink error (nothing electrically wrong with it).

Looks like H0301 on the datecode. No surprise since it's in the middle of the bad era for the Nichicon HN/HM series.

Re: The Hall of Shame - Badcaps Photo Montage

Is that computer an SFF style machine?

If so, not surprised. Those computers are a true test for capacitor thermal ratings.

Bunch of Nichicon HM's from old HP D510S/845G. To my suprise, powersupply was full of HZ and alike, all good.

Seen plenty of bad WB series caps, they also fail open without any visible signs as well. Replace all of these caps, not only the bulged/leaked ones.

Re: The Hall of Shame - Badcaps Photo Montage

Samwah WB series from a Samsung TV (Hansol?) PSU

The bulging caps are 1000uf 25v, there are also 1000uf 10v caps that while not bulging, may also be bad.

Re: The Hall of Shame - Badcaps Photo Montage

Well, the low-end Athlon II X2 chips are just only slightly faster than the older AM2 X2 chips clock-for-clock, so no surprise there. That said, once you go above 3 GHz, they're very decent for everyday use.

Athlon II X2s have K10 cores and are significantly quicker than K9-based AM2/2+ X2s. However, they're better in AM3 mobos with DDR3, and do fine in AM2+ mobos also.

That said, the Sargas K10 Semprons 14x are the real sleepers - they work fine in AM2+/AM3/AM3+ sockets with modest idle power consumption and are pretty nifty even when loaded, with CPU power consumption rarely exceeding ~25W. They can also be OC'ed significantly, but I never attempt that. These are the modern-day equivalents of the venerable Tualerons, ~15-20 years later - perfect for 24/7 appliance boxes and HTPCs. Small-footprint distros like Lubuntu 18.04 (Alternate) are perfect for these - Sargas runs fine with dirt-cheap 2GB Kingston DDR2-800 on AM2+ running Lubuntu.

Whole lot of toasty badness going on there, ruky con!

Taicon BY 22uf 250v.

This is in an older Feit Electric LED bulb that has a LED with a corner burned off.

Re: The Hall of Shame - Badcaps Photo Montage

Well, on one hand I'm pretty sure that's a low quality brand, but on the other, it's about 12 1/2 years old. Even if it has needed hair dryer help for 2 years, that's a reasonably decent life.

Thanks for your comment PeteS - that's a valid point, and I'm not particularly upset about the failure - I just added the pic for interest. The cap is mounted against a heatsink too, which likely also had some bearing on its failure.

Re: The Hall of Shame - Badcaps Photo Montage

Found the attached slightly vented capacitor in an xilence 1000W ATX power supply - when issue first surfaced, the supply would only run on warm days, so it had a couple of months of being assisted with the gentle application of a warm hairdryer, though eventually it gave up altogether. This capacitor appears to be the only one showing signs of failure, though I've not replaced it as yet.

Re: The Hall of Shame - Badcaps Photo Montage

The font on those “Nichicons” is definitely dodgy, although I’d be curious to see if the bung is accurate or not. My guess is that they are most probably counterfeits as well.

Re: The Hall of Shame - Badcaps Photo Montage

A while ago I bought an Ebay source for an old qosmio toshiba, when I got the source, I was curious to disassemble it, and I found Nichicon capacitors, but obviously fake xDDD.
The impression and the color of the label gives them away.
The capacitors have not yet failed, although copies will not last long, so I'm going to replace them.

Re: The Hall of Shame - Badcaps Photo Montage

Oh I have a good one! A NAD T752 amp filter capacitor let its goo out. Nice amp but the choice of capacitor is questionable.



(other images hidden)

Take a look at how wide open the vent is. I'd say it suffered a sudden, violent failure.
That's not the first time I've heard of big filter caps going in a NAD amp..

Found this in an ATX supply and I thought it might be interesting: not sure if that white "fog" is directly related to the bulged cap, but I believe it is, since I haven't seen anything like that so far...what is that ? Has anybody seen this before ? :| Does electrolyte "vape" like that ?

Look closely at the big filter/regulation choke hiding behind the wires. I think it has smoked, has it not? Looks a bit dark/burned.
I'm betting that it may have had something to do with the capacitor failure, causing the choke to run hot. Once hot enough, it probably develops a short (or looses magnetic properties) in a winding, causing a more significant incident~

//-------------//

Anyways, I've got some specimens of my own to share.
The notorious Samsung SyncMaster 204T, with failed SAMXON ("Sam's Gone") GF ("Go Figure") caps.
The bung has pushed out, and a little crust built up. Who fed this cap some Taco Bell?

The bloated cap measures a measly 51uF, and the other measures about 340uF. Both way out of spec.
NOTE that the non-bulged cap has a wet appearance on the bung, I think it has been leaking!
The CapXons (GL series) *appear* fine, but I'll replace them anyways.

Re: The Hall of Shame - Badcaps Photo Montage

I.Q. are actually just a bit unpredictable. I still have an Compaq Sniper socket 7 mobo with those I.Q. caps still reading normal. That motherboard also has 3 large Fuh Yin caps on the built-in audio amp (which uses a full-blown TDA1517 IC mounted on a mini heatsink! ). Haven't pulled those, but being in the audio section, they might actually still be reading OK. Probably because they are GP caps and not low-ESR, I imagine. Even the really crap brands don't do that terribly bad when it comes to GP caps in low-stress GP applications... though they are still quite more problematic compared to any good Japanese GP series.

Wasn't I.Q one of OST's subsidiaries?

Re: The Hall of Shame - Badcaps Photo Montage

I think Tayeh just rebranded other random crap. I've seen some that looked like GSC caps and some with other series and date code markings that I don't recognize. I have a modem with Tayeh caps that only have capacitance, voltage, and the temperature rating printed on them.

I still see Fuhjyyu caps in power supplies.
