Very surprised to see Sanyo listed as "bad cap". What was the experience that caused a listing?

i have seen some in ccfl inverters that may have suffered from excessive heat.
i have not seen any fail on a mobo.

Same here... I use Sanyo when I fix mainboards, powersupplies, switches etc etc... Never ever seen one fail...

I vote for having them on the good caps list...

What some people may interpret as PCE-TUR is actually a "JP" logo, and the series is "CE-TUR". "CE" probably stands for "Capacitor Electrolytic" and "TUR" is the series (I found data for the TUR series on http://www.0759.net/products/ecap/ecap_e/14-15.htm which may be correct, even though the pictues on the site do not show the "JP" logo). Probably "JP" stands for Jen Pan.

Just spotted a slightly bulging Sanyo 1500uf 6.3v on an Asus P5A-B that has been giving my sister some problems. The board doesn't always POST (especially when one resets it after it's been running a while), and it frequently loses contact with the ISA slots.

The rest of the caps consist of one OS-CON and one Rubycon. All others are Sanyo and look to be in great shape. The board is nice and stable when you can get it going. I'm just going to replace that one Sanyo I think and see how it does.

Re: bad cap manufacturers - please post yours here

That's strange, please post pictures and also what model it is...

Is it right next to something that gets really hot?

[Oklahoma Wolf]

Re: bad cap manufacturers - please post yours here

I'll have to wait to recap it for pictures, but will make sure to post one at that time. Forgot to check what model it is. The cap is the largest on the board and is right next to the memory slots about 2" above the AGP slot. It would have been directly above the STB Voodoo Banshee the board was running, which used to burn my fingers if I touched the heatsink by accident (I put a fan on it when the boot problems showed up).

Every other cap on the board looks perfect.

Well, the Sanyo wasn't bad (I think) - replaced it anyway with a Panasonic FM as long as the system was apart. The mystery of the flaky Asus P5A-B continues. Found out the USB ports are dead on it too.

Re: bad cap manufacturers - please post yours here

Dead USB is usually caused by absence of 5V - because of blown fuse or broken/burnt trace somewhere.

Re: bad cap manufacturers - please post yours here

Yep - couldn't find anything obvious on the board though so I left it alone.

Wendell? 1000uf 6.3v + pulled from flakey PowerVR/STM Kyro 32mb video card.

Also found this : Since the 1980s, a solid "electrolyte" (actually a semiconducting polymer called 7,7,8,8-tetracyanoquinodimethane, or TCNQ) aluminum capacitor has been available from Sanyo under the OS-CON name..http://my.execpc.com/~endlr/electrolytic.html

what is oscon doing on the badcap manufacturer thread? anybody seen a bad oscon? i doubt it...

[bobcaygeon]

Re: bad cap manufacturers - please post yours here

not sure if this is a one off occurrence, but heres an "Elite" brand capacitor I pulled out of a NEC FE2111SB monitor. Not sure if you can tell, but the cap is bulged to the point that the cap is tipped in the photo. The picture on the monitor was best described as slightly jittery, and replacing the cap with a Nichicon of equivalent capacitance/voltage (either that or ripping the entire monitor apart and putting it together again) has solved the problem without reoccurrence after 2.5 months.

My bad, .was just showing the connection Sony->OS-CON. ...Reg

Re: bad cap manufacturers - please post yours here

My EPoX 8RDA3I Pro has Rubycon as voltage regulators and Panasonic (Matsushita) everywhere else I can see with it installed, my PowerColor Radeon 9250 has Panasonics as well, and my (I think) Lite-On ~350w PSU is all Teapo. Yep, I think I'm doing fine. I have a few old AT supplies with Rubies and NCCs that I'll use as secondary supplies as I need them, this one included.

[Shroomie]

Re: bad cap manufacturers - please post yours here

Ah darnit, no way to reply?

Anyway, the only ones I've seen fail have been Fuhjyyus in an Antec PSU (the little guys) and a few Canicons in an unidentified PSU. The latter has two intact Fuhjyyus as the big cans...goes to show how bad Canicon really is...
