Re: Teapo



The ones that I've been replacing have been 10mm. I think my failures have been heat related though. Just an estimate from what I've seen, but I'd say 50% of them have gone bad after 3-4 years of near continuous use. [URL="https://www.badcaps.net/forum/showthread.php?t=16772"]Link to my original thread.[/URL] At the time I posted that thread, only the ones closest to the heat sink were failing. In the year after that we've seen all of the positions having failures.Re: Teapo

Re: Teapo

I voted junk, but if they're kept cool they can last. We have about 1500 Entone brand IPTV set top boxes, the DVRs are the same as the non-DVRs, except they get a fan and hard drive.

On the DVRs with a fan, the Teapo capacitors fail very rarely. The non-DVRs on the other hand, have almost all had at least one capacitor fail after 3-4 years. There are six 470uF 25v capacitors in each set top box.

This could be blamed on bad set top box design and poor cooling, but I don't think that the boxes get much hotter than any other consumer electronics....

Re: IPTV set top box repair question

Thanks for the help guys. We're not sure why they fail, could be heat, they're mounted a little less than a cm from the processor's heat sink. I measured voltage across it when the box was running, and it measured 3.334VDC.

It'd odd, because there's quite a few of these types of capacitors on the board, but it's consistently this one failing, never the others. Could be a design flaw too I guess....

Hello everyone, I work for a company that provides IPTV service and we have several set top boxes (50+) that share a common defect with a capacitor manufactured by Teapo. The capacitor is a 470uF 25v SY series. I believe it is the 10x12.5mm one listed in this datasheet: [URL="http://www.teapo.com.tw/ftp/pdf/SY.pdf"]http://www.teapo.com.tw/ftp/pdf/SY.pdf[/URL] .

I was wondering if the Panasonic FR series would be considered an appropriate replacement for these. Specifically I had these in mind: [URL="http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=P14419-ND"]http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=P14419-ND[/URL]...
