Wich caps are best?

Are Teapo better than Capxon??
Are OST better than Capxon but worse than Teapo?
Are Teapo worse than jananese ones but better than OST and Capxon?

Re: Wich caps are best?

Best is not a word commonly associated with any of the makes you mention.
They are all poor at least as far as most applications we see on here.

Teapo is mediocre/ok for psus.

Ost is bad/mediocre.

Capxon is terrible! I see them failing everywhere.

Re: Wich caps are best?

Thank you guys for your replys.

Sorry I forgot to mention that I meant for SMPS use. So if a PSU has wich caps, wich are the better ones of the ones I mentioned.

Teapo is OK. They're used in a lot of hardware with low amount of failures. Lots of power supplies are used daily with Teapo caps with no problem.

OST, I don't know. Not much experience with them but this forum is full of OST caps that just... go bad without signs of failures.

Capxon is really bad, anything low esr will eventually die.Same with Samwha capacitors in Samsung monitors.

The primary capacitors (high voltage) are probably fine.

Anyway, this subject keeps popping up, everyone has their horror stories, you won't find a common consensus.
I personally wouldn't put Teapo in the same group as Capxon.

I am not sure you are getting the point - most of us just wouldnt use them given the
numerous better alternatives.
Perhaps if you were to tell us why you are asking which are better - anyway goodpsusearch has already answered you.

Re: Wich caps are best?

The point I'm making is that I would have no problems using Teapo for low stress locations or stuff like CRT TVs, radios, dvd players etc.
Sure, they're not good for VRMs and hot locations but the volume of capacitors they sell and the high volume of various power supplies on the market using them assures me they're not quite shit.
If I were to fix some cheap 30-40$ power supply, I'd use Teapo for anything but the 5v standby with no worries. As long as there's a decent airflow, they'll last a long time.

Someone that brings me a 30-40$ won't agree to spend 10$ on 6-8 Panasonic or Nichicon capacitors.

I can't same the same thing about OST, it's too much of an unknown for me.
As for Capxon.. pretty much in any monitor or power supply with locked/dead fan, you'll see blown up Capxon or Samwha capacitors.

I like to use Nichicon, UCC, Panasonic, but with low esr series from Nichicon being discontinued and Panasonic being expensive at low volume, you have to be open minded.

Sure I wouldn't use them because I have alternatives, if it were to fix things for my own use.

But to even ask if Teapo are better than Capxon, it's silly. Yes, they're much better.

Well, I don't want to use any of them to recap a PSU or use them for a defective motherboard. I just wanted to know wich of them you would rate how. For recapping a PSU I'd use NCC or something like that...

Re: Wich caps are best?

I read a little, thought a little and came to the conclusion that you have to read many many datasheets to find a cap of your choice...

As for Teapo:
The SC series is rather cheapish and way worse than any other low ESR series Teapo has right now.

And did find some numbers for a couple of Teapo caps:
Here some numbers for 16V/2200uF Teapo Capacitors:
Size, Riple Current, ESR
13x25 2230 0.027 for TA Series, 10k Life
13x20 2480 0.023 for TB Series, 6k Life
13x20 2480 0.019 for TC Series, 10k Life
13x25 2770 0.018 for SJ Series, 5k Life
13x25 2230 0.027 for SY Series, 6k Life
13x25 2230 0.034 for ST Series, 10k Life

The Standard ones:
10x30 1780 0.032 SC, 2k Life (Downsize)
13x20 1720 0.033 SC, 2k Life (Downsize)
13x25 2000 0.028 SC, 3k Life

And there is no 2200uF/16V cap for the SZ Series.
But a 1800uF:
10x25mm, 2546mA, 14mOhm


In Short:
The TC series seems best with the lowest ESR and long lifetime.
SY and SJ seems OK so far.
SC not so much...
And you can't blame Teapo if they fail but the one using those cheapish caps (manufacturer of the device)...
And that's mostly the problem that caps are sometimes rather abused...

As for other caps:
It seems that some manufacturers had some problems around 2007 but if you've taken a look at some datasheets you'll find something like a year next to the series.

Like (for CapXon): 2014 KF or GF Series.
And the specs for the caps also changed.
The GF series became a 5000h lifetime one instead of a 2000h one they were some time ago...

That doesn't help us much because we don't just have to look at the datasheet, we have to get a datasheet that fits the vintage of the cap. And that can be hard at times...

And I don't think it has to be a japanese cap anymore. Those times are gone.
Even some guys at TDK Lambda say that the manufacturer does NOT matter but what you want and what you are willing to pay!
A high(er) quality capacitor does not come cheap. And I doubt that there is a huge difference with life as well as cost of those caps.
