Aopen AX37 Pro

Got two of these baords yesterday. They have managed to put two Lelon caps on these boards (both bad on both boards) besides high-quality (I guess...) Rubycon YXG-s (who produced the smaller blue 1000 uF caps seen on the third photo?).

the blue caps look like united chemi-con but there is no series TMY found at united chemi-con. an internet search revealed no data on TMY therefore they may be crap and are imitating the look of united chemi-con.

I have seen this on an Albatron PX-865PE board where amongst the 1000uf 6.3 United Chemi-con KZG which are little brown caps, they put also a few EVERCON 1000uf 10V caps which are the same colour and with the same vents as the United Chemi-con caps. Only the writing on the caps is different.

It is curious that the TMY imitate exactly what chemicons look like. perhaps i am wrong?

Rubycon YXG is at the bottom of the series of their caps relevant for motherboard applications, used because they are the cheapest i guess. An OK but not excellent choice for low ESR, the ZL series would be a better choice. At least they will not fail.

or maybe it is a discontinued product? i am also trying to find the data of (look alike) chemicon LXF, chemicon "sam young" (<- is it really chemicon?), panasonic FJ (<- the top and the bottom seal are exactly like panasonic), and samsung ssl...

its amazing how good those company hiding the data sheet of their product... for example, i can't find the datasheet of the good old HFQ panasonic anywhere, even on their website... but finally found some link on a europe site about the comparison of FC and HFQ. maybe panasonic already kill the link for HFQ or other discontinued product.

chemi-con discontinued series

http://www.chemi-con.co.jp/english/c.../daigae_e.html

they should just point to google instead of having an index.htm in their site. so much hidden information.

LXF replaced by LXY

Samyoung Electronics http://www.samyoung.co.kr/

Since May 03, Samsung no longer make electrolytic capacitors. Their division taken over by Samwha Electric http://www.samwha.com

no need to worry too much about HFQ for our applications, it is probably quite similar to FC.

Replaced the vented Lelons with Panasonic FC-s and both boards passed my stability tests
