I always stick to the top 5 when recapping stuff, but some bad cap brands don't seem as bad as they seem. I've seen lots of Taicon and Elite capacitors handle a lot of heat for a long time and still hold their specs well. Taicon in some hold hot running PSU's, and Elite caps on the output filtering of monitor power boards that are really discolored from getting so hot and the Elite caps are almost never bulging and usually pretty low on ESR still. But doesn't Taicon have some ties to nichicon?

Re: What do you think is the most underrated "bad cap" brand?
if a cap doesn't have one of the autographs in my signature below, I don't put it in a customer's equipment! (or my own)
I make a crazy profit on recapping expensive equipment, why would I want to cut corners on a cap that only costs me 25 - 75 cents in the first place?Last edited by theOracle; 06-12-2013, 09:47 PM.__________________

Taicon capacitors are probably okay in a SMPS or low heat/low stress environment but Taicon's "HD" (AKA their HF series) series is notorious for failing on motherboards within 3 years' time (not 24/7 use). I would say they're about equal to similar-tier Taiwanese capacitors, IE Teapo, Jamicon, Ltec, maybe OST, etc. For what it's worth, Teapo and Jamicon do obtain their electrolyte from Japan (at least I trust them on that much, and probably Taicon as well, not sure about any of the other Taiwanese or Chinese brands, though), even if the rest of the materials they use are of underpar quality.
The most underrated bad cap brand... probably Taicon but then they are somewhat related to Nichicon so that might be an unfair assessment to procure. To be honest, since Teapo gets so much hate and since I often see Teapo last a long time in old and well designed PSUs, I might just say Teapo is exactly that. Yes, though, I also think it's always a bad idea to use anything but Japanese capacitors (or capacitors whose materials are obtained in the US or UK).

As far as the best Japanese capacitors go (lytics wise), I'd go with Panasonic/Matsushita... I believe they have the lowest failure rate out of all the Japanese brands.
EDIT: That's four series, KZG, KZJ, KZV, and TMV.Last edited by Wester547; 06-12-2013, 10:48 PM.

Re: What do you think is the most underrated "bad cap" brand?
Yeah, I never said I keep them, just that they don't seem to always be bulging every time I see them (Like CapXon, Fuhjyyu, Teapo) I've only ever reused Elite caps on the primaries of old non PFC PSU's.
It's so hard to pick a favorite among the top Japanese brands but I've been really leaning more towards Rubycon lately. They seem to be the best with size/ripple rating/heat tolerance ratio. With Panasonic in second

Chemi-con makes more capacitors then all of the other Japanese makers combined, and with the exception of one series, they have been flawless!__________________

Re: What do you think is the most underrated "bad cap" brand?
yeah I agree, all else being equal, gotta love those Rubycons!
my Japanese friend who has over 100 patents and works for Sony puts it this way:
"As in beer, when you make capacitors, it's the water!"

Re: What do you think is the most underrated "bad cap" brand?
I'd have to go with Teapo and Samwha... They can be hit and miss, and I've seen Samwha caps last when they're used under spec."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine! We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

Re: What do you think is the most underrated "bad cap" brand?
I second that. Teapo SC/SEK caps lasted 5-6 years in my PSU before giving up. I am typing from the same PC which is still working 24/7 with a new old stock PSU (from 2010), without even the slightest sign of failed caps on the mainboard (which mostly has Panasonic and Sanyo).

Re: What do you think is the most underrated "bad cap" brand?
Well, I just lost a long rant I was going to write about my suspicion that 8mm Teapos are less reliable not because of a manufacturing defect but because Teapo derate their endurance ratings (by 1,000 hours) based on not only case sizes but based on the down size of standard case sizes that would otherwise be 3,000 hours @ 105*C (Teapos are rated at 1,000 hours-3,000 hours @ 105*C, so many of those 8mm Teapos are derated from 10x12.5 standard case sizes which means they're rated at 1,000 hours... maybe that's why they fail so quickly? G-Luxon is the only other brand I know that does that and they merged with Teapo in 2006... 5x11-10x12.5 Teapos by standard sizes are rated at 2,000 hours, 10x15 and higher 3,000 hours). 8mm Teapos are often found in the +5VSB output, or near heatsinks, diodes, resistors, coils, or in poorly ventilated and cooled printer and LCD power supplies..... is that what you mean with respect to 8mm Teapo SC failures?
Of course, I could be reading too much into nothing and it might just be inconsistent quality as with any other Taiwanese brand, or it could be a dive in reliability since the G-Luxon merger. And I know the endurance ratings aren't wear out tests so they aren't truly valid. I just noticed that Teapo and G-Luxon derate the endurance rating not just because of case sizes but because of non standard case sizes which would otherwise have the standard and full endurance rating, which hurts their longevity... and there have been ample Su'scon failures documented on this forum. They might just last in low stress applications.
More simply, the point Heihachi might have been trying to make (I can only speak for myself) is that while Teapo's bad batches are obviously bad, their good batches are of merit and can last as long as 30,000-50,000+ hours given the right conditions (not a surprise since to my knowledge, Teapo obtain their electrolyte in Japan, so the aluminum foil/cans are the real problem).Last edited by Wester547; 07-17-2013, 04:51 PM.

Re: What do you think is the most underrated "bad cap" brand?
I'm rather surprised that Panasonic caps are held in such high regard here. I've recapped a couple Panasonic TV's, and the Panasonic caps in them, while not bulging, were very under spec. The TV was about 10 years old at the time, but I've pulled out good caps on TV's twice that age.
For me, I prefer Nichicons or Rubycons.
