IIRC, the KMG series is a high-quality general purpose series, not really suited to P/S O/P or MB VRM usage.PeteS in CA

Re: The GOOD Capacitors Thread!!
I looked at my receipt and they're listed as United Chemicom but on the caps it just says KMG, and has the little logo of a shield?
I bought them with the intention of going on to MB's and PS's, and that's where they'll be going. Cant be any worse than the crap that was there originally.
The various caps I've seen puking all over MB's and PS's look like basic consumer grade stuff, just like in everything else.
Wouldnt calling any consumer grade cap "general purpose" be accurate?Comment

Re: The GOOD Capacitors Thread!!
General Purpose....now I see after doing some reading on Chemi-Con's site.
Next time I buy I'll be more specific as to my needs.
Always nice to learn new things, thx!
But these will still be going into my ECS P3 Tualatin mobo.

The location may be the killer depending on the video card or PCI cards involved. Odd though that only that one cap appears to have failed. I am going to replace it and see if the board recovers.Attached FilesComment

Re: The GOOD Capacitors Thread!!
I find that BEC and ACE caps are pretty good. They've been around for some time, my 1983 ibm pcjr has all ACE caps on the mobo, and the BEC on the modem.

Re: The GOOD Capacitors Thread!!
I received some Rubycon capacitors with the plug at the bottom extended out from the can not quite 1mm. Other than this the caps seem o.k. When soldering to mother board, these caps will not be flush and is this a sign that the caps are defective?Comment

Re: The GOOD Capacitors Thread!!
That's intentional.Originally posted by edbog
Most caps have extensions [legs?] on the bung [rubber plug] to prevent them from sitting directly on the board. This allows cleaning the PCB [not necessarily a motherboard, ANY PCB] without trapping any solvents or liquids under the cap [because that might cause a short when it's re-energized after cleaning].

Re: The GOOD Capacitors Thread!!
Thanks for the information. I am very new to all this.
I'm working on any Apple, iMac, iSight model mother board trying to change some capacitors.
This may be the wrong forum but have you or anyone else worked on these Apple board? Is there any wiggle room for installing 20mm capacitors instead of the shorter ones or will the longer ones make contact with anything that they shouldn't in the tight space?Comment

I haven't worked on Apple/MAC boards but I'm sure a few members have.

Re: The GOOD Capacitors Thread!!
Hello.
Much as I hate to say this, I've noticed several Perfectly Good OST brand caps, even after years of usage.
In particular, I just did a major upgrade for a close friend.
The system was an ECS board with OST everywhere except vCore, which were tiny little UCC 820uf/4v caps powering a hungry Prescott 630. All of the caps on the board looked great with no bulging of any kind.
The system has been running 24/7 since late 2006 and hasn't seen an air conditioned room until 2009. Big time dust everywhere so everything was nice and toasty. Yet the system was entirely stable and never a problem.
So, just for some desolder and resolder practice, I pulled out the 1500uf/16v OST RLX caps with date code 0603. All tested good at around 1400uf and .01 ESR.
I happen to know that this system has had a rough life. Continuous run time, hot summers, cold winters lotsa dust and a hot Prescott CPU.
Still, the ultra-cheap OST on the ultra cheap ECS P4M800 survived and did fine. The PSU remains an Antec SU-380 full of OST. I regret not putting it on the Load Tester and Scope.
Could Lousy Crummy OST have gotten their act together around 2006 or so?
It appears so from this sample and others.
Have Fun,

Re: The GOOD Capacitors Thread!!
I have noticed this too.
My old ECS RS482-M754 has all OST caps everywhere and it still runs like a top and has no bulging caps. I bought it late 2007, it was one of newegg's "cpu/mobo deals," meaning it is a old new stock motherboard with a old new stock cpu that they still have on the back shelf they don't need anymore.Comment

Have you two lost your minds?

Bad brands of caps are not GUARANTEED to fail every time.
They are PRONE to failure and have high failure rates.
-
If ALL of them failed then the companies wouldn't be around to keep us in business anymore.
Maybe not. .. They still make Fuhyyju don't they?
Some times Fuhyyju last for years too.
I have some in a 7+ year old PSU that are still fine.
- Shall we tag Fuhjyyu as good caps too because of it?

Razz complete.

Could they have gotten better. Yeah, any of them -could-.
My thinking is similar about Teapo after 2005-2006 but I haven't found any counter examples with Teapo.
- OST is easy to find counter examples for.

Re: The GOOD Capacitors Thread!!
I would have said no to them also, I've got a MSI 945GZM3 with bulging Teapo SM 1000uF 6.3V, dated 12/05, around the memory slots. The 680uF 4V OST RLAs, dated 0618, on the board used with a 800 MHz CPU measures fine in circuit, but will replace them also when I get around to recap the board.Originally posted by PCBONEZ------------

Teapo don't seem to get used that much on motherboards anymore and since having them at all is less common, reports of failures is less common.

hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
it has inside:
2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
2 x 470uf 16v LZ105c branded as G.Luxon
not heard of these brands are they any good?

Are there good brands for 'run capacitors' or 'start capacitors' that are used on electric motors or heat pump compressors? ... r are the good capacitor brands for electronics (power supplies, laptops, motherboards, etc.) also the good brands for run capacitors?

I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
