Re: List of Bad Cap Manufacturers

Wow, what an eye opener.
Did not even realize there were THAT many brands of Elytics....but I am not into computers.
In the guitar amp world we pretty much see:
TAD
F&T
IC
Xicon
Nichicon

IC had a bad run of 20/450 axils a few years back. I guess it was the whole... bad Elytic Paste scenario.
Other than that, we do not see any failures to speak of.

Yeah, Nic components had some bad runs of capacitors too.

Never heard of TAD capacitors, have any pictures?!

Re: List of Bad Cap Manufacturers

I've never heard of this brand either. This Anodia 1000uF 16V cap was in a dead Telstra TT-300-6B cordless phone wall wart from 1997. Transformer was open on primary (19 ohms on secondary).

The negative stripe is identical to Su'scon. Note the basketball-shaped vent...

I've seen those a few times. All were good, but yes, they are old.

Re: List of Bad Cap Manufacturers

Are "GRP" caps cheap Chinese junk or otherwise? They are apparently made by Zhaoqing Hongyi, but for no reason whatsoever, they put Matsushita 'M' logos on their caps.

Pulled a GRP 3.3uF 450V CDT series from a smashed CFL recently. This one has a Y-shaped vent, a plain flat bung and a Nichicon style negative stripe complete with rounded negative sign, however the negative sign itself is much longer than Nichicon's version.

It seems that there are a lot of Samxon failures going through this thread, are they really as good as people think? Going by the number of blown Samxon caps of varying types, including mine above, they are seemingly of the same quality as the infamous KZG.

Do you have any pictures of it?

Thank You
With original caps monitor worked for about 5 years.

Re: List of Bad Cap Manufacturers

No. Samxon GF are just as bad as CapXon. That said, if it held a few years with the CapXon, it'll last a few more with Samxon GF, so it's your pick.

Re: List of Bad Cap Manufacturers

Hello. How Samxon GF series caps compare to CapXon KF caps reliability wise?

Found 3 bulged CapXons in Samsung 205BW monitors power/inverter board. It is relatively easy for me to get Samxon GF caps from one local supplier. Is it worth to recap monitor with Samxon GF?

Re: List of Bad Cap Manufacturers

My Hisense LCD TV (HSL5529HDI) died on me yesterday. Turned out that there were at least three bulging Samxon GD caps on the PSU and another bulging one on the main board. Date codes for the TV: PSU 0833; mainboard 0838; rear panel plastic Oct 2008.

During the last successful power up of this TV, the backlight slowly faded on from right to left before hitting full power; the second power up attempt didn't have any fault (this was only done about a minute later so the caps were still fully charged); during the third power up (after leaving it unplugged and switched on for a while, discharging the caps) only the blue LED came on and that's where I gave up and took it apart. Eleven screws later, I managed to remove about an inch of the rear panel; turns out that there are nearly a dozen clips holding the two plastic halves together. Additionally, the LCD panel itself may now be cracked after trying to hunt around for said clips. Can't make it just fall off after taking out a dozen or so screws, can they? The only thing they didn't do was glue it shut like a wall wart...

In fact, I will now put up a few post-mortem photos in a new topic.

Re: List of Bad Cap Manufacturers

Samyoung was founded in 1972 as a joint venture with nippon chemi con / united chemi con...
In theory, being so old and with such company backing them up they should be of good quality.

However, I'm not sure where I've read or heard that at some point they sold Evercon/Sacon/GSC capacitors series under their brand (to have a larger catalogue of capacitors)

Evercon/Sacon is shit so who knows.

Re: List of Bad Cap Manufacturers

I see that this thread hasn't been updated in awhile, but it is very interesting reading. I would like to add some suspicious caps to the list if I may. I opened up a Sony VCR, which was bought in 2008 or maybe 2009. Nobody makes VCRs well anymore, and probably for good reason, but I was surprised to get a Sony that was such crap. None of the caps appears to be bad, but in two different places on this board, I've got resistors that have burned up so badly, I am surprised I didn't have a fire to deal with. I have no doubt that if I bothered to test these caps, I would discover that they were the real culprit. But in this whole thread, I didn't see mention of them, so I wanted to add... they are labeled "Sam Young". I can only see two different types of caps... CapXon and Sam Young.

Re: List of Bad Cap Manufacturers

I bought these antel caps to re-cap the secondary side on a baird lcd tv.
I have bought the same capacitance and voltage ratings but the antels are just
too wide on the lead spacings to fit. I guess i will have to measure the lead spacings and look else where.

Re: List of Bad Cap Manufacturers

Does any one know of antel caps , Are these any good , i bought some off a supplier but i can't find any information about where they are made or quality.

Dont look great - small chinese producer - even crap cap manufacturers give more detail.
probably just badged rubbish, but perhaps someone knows better

Ask your supplier?

Re: List of Bad Cap Manufacturers

Odd... After putting together a ESR meter I went through my cap collection, which includes new ones that I may use for prototyping for the heck of it. I found a brand new NIC capacitor that had open ESR... A 35V 220uF 105C unit. I noticed the bottom was kind of sagging and pressed it in... Some liquid oozed out! Into the bad caps pile it goes. I couldn't believe I had a -new- cap that didn't get soldered or even stuck into a protoboard (since the leads were different lengths like if it was new, I highly doubt I used it before!)

I would hope this is not typical of NIC capacitors, but it was one bad apple I got...
