Because they build these crappy electrolytics, everyone and their dog loves to put into their appliances, in an attempt to artificially limit the useful lifetime of the gadgets and thus maximize profit by forcing the users to replace them in short intervals?
Sorry, couldn't resist... ![Face Palm :palm:](https://www.eevblog.com/forum/Smileys/default/xfacepalm.gif.pagespeed.ic.EBDwh1hCfo.png)
Hmmm. Therefore, ALL engineers are morally bankrupt.
The crappy capacitor manufacturers are merely supplying the market needs of the morally bankrupt engineers out there (which by the above reasoning, is everyone). A question best left to the philosophers ![Wink ;)](https://www.eevblog.com/forum/Smileys/default/xwink.gif.pagespeed.ic.cldandycH0.png)
It's more likely that the engineers just design in a capacitor they know to work well and then they're replaced by the penny pinchers with a "that'll do" type of lower cost. Dave makes a similar remark on the PSU in one of the repair videos of a Samsung monitor, the PSU being designed rather well and then let down by the quality of the electrolytics that was probaby the result of the designer's choice being overruled by a moron who had to "optimize" design cost.
In industrial electronics, the use of no name brands seems to be a "no go". Most designs that go back a while use Vishay/BC if they originally had Philips caps, and the other brand I see the most used is Nichicon. Followed by Panasonic, Rubycon, Nippon Chemicon and Yageo.
In a recent tear down, there was a Lelon cap in the PSU of a Siglent scope and Dave made a negative remark about that one. I'm wondering about the validity as I have seen them being used in industrial electronics.
About CapXon specifically, I have yet to replace one of those. The most failures of swollen 'lytics I've come across are those
green Low-ESR types of really obscure brands like e.g. JeWe...
I found similar cheap crap had failed in the plugpack of one of our JTAG testpods. Such an expensive device supplied with such a cheap PSU
