What are you, a law partner?

OwO

please no

Favorite brand of caps?

They all let you down at some point

rubycon is gud but vishay is pretty fucking based and has a pimp name.

>not going for the based kys caps

I dunno, 40 years of 24/7 operation before a cap finally failed seems like a pretty good run. Not like they're hard to replace either.

at least you can see what's wrong. When your PSU stops working and you don't know if it's a cap since nothing is leaking or bulging or if it's the HOT or the transformer then THAT is when you can complain.

Usually you can tell it's a cap without even opening it if the failure is load-dependent.

Nichicon or Nippon Chemi-con for that weeb cred

Paecifically I'm complaining about a CRT TV PSU. Not much way to test unloaded.

>BASED JAPAN

en.wikipedia.org/wiki/Capacitor_plague

Industrial espionage was the reason. A Japanese manufacturer created a fake electrolyte recipe and allowed it to be stolen by the chink copiers.

>In 2001, a scientist working in the Rubycon Corporation in Japan stole a mis-copied formula for capacitors' electrolytes. He had first worked for the Luminous Town Electric company in China. In the same year, the scientist's staff left China, stealing again the mis-copied formula and moving to Taiwan, where they would have created their own company, producing capacitors and propagating even more of this faulty formula of capacitor electrolytes.

imagine the smell

OwO

It's not just caps.

It actually doesn't smell all that much.

the fuck happened to them? those are not lithium ion shits

They're lead-acids from a 192 V string with no cell balance monitoring, so when cells start shorting out with age, the voltage across other battery blocks will rise and rise, until they start passing a lot of current and get very, very hot. Hot enough to melt the label off.

With the whole RoHS scam electronics often fail way before a capacitor would go out
While the capacitor plague was a problem the real killer of reliability for consumer electronics was the introduction of lead free solder

Don't you prefer throwing everything away every two years due to tin whiskers? Much better than leas frequently returning lead to the earth from whence it came.

At least those fail in a quite subtle manner.
Its not the pyrotechnic show that are the tantalum capacitors when they eventually fail.

when are hardwarechads going to rise up and kick these crossdressing programming fags off our board?

It’s not even tin whiskers that are the biggest problem
A good enough shock in transit can make something non functional before it even gets in your hands
Over time thermal cycling can break joints
They say there is not enough evidence to determine what is more reliable but it’s really strange how anything defined as “mission critical” gets an exception from the RoHS

Tantalum cap failures are almost always a side-effect of the power supply going out of spec. The MTBF is over a hundred years and up to literally a thousand goddamn years at low temperatures. But if you go over their rated voltage by the tiniest fraction for even an instant you can kiss that cap goodbye.

Don't they grow crystals over time that just short the thing?

/diy/ is the actual board for men.
that it is pretty underpopulated and therefore slow says a lot.

Wrong type. Those are manganese dioxide tants, which can actually withstand large voltage spikes (like 4x in some cases) but have a far shorter MTBF because of field crystallization.

Interesading.

Have you never recapped anything user?

did the ones on the right come from a mirror universe

>the real killer of reliability for consumer electronics was the introduction of lead free solder
DINGDINGDING WE HAVE A WINNER
This was why the 2013 MBPs with discrete GPUs failed after 2 years in anywhere with a cold climate.
This was responsible for a similar failure in HP Lifebooks AND the RRoD in Xboxes.
The engineer who created surface mount tech died before the EU mandated lead-free solder and no one bothered to find out that most solder balls have voids in them. Lead being pliable doesn't care about a GPUs hot/cold cycling but tin alloys are basically GLASS and voids cause cracking.
