Can anyone help explain what happens to an electrolytic cap "Panasonic" 22,000 uF x 63 volts, thus exploding. It was bought at a bargain store Analog Metric (Panasonic 22000uf 63V AUDIO Electrolytic Capacitor_Panasonic_Capacitor_Analog Metric - DIY Audio Kit)
thank you

These only seem to be available from HK sellers. I can't find a similar Panasonic capacitor from any reputable distributor. The closest match I can find is 40mm in diameter, not 35mm.
It makes the situation even more suspicious that the seller you linked to also sells a nearly identical "Hitachi" cap....

The OP bought the parts from a dedicated webshop, not ebay. Yes ebay is an easy outlet for sellers of fake parts, but to say that one should never buy any parts on ebay because they're all fakes is a little extreme.
Most of the time it's pretty easy to get an idea if the parts you are buying have a high chance of being fakes or not, you just have to pay attention and maybe do a little research.

They look very dubious to me. There is a reason that the cheapest decent caps are about £10 each for 63v 22kuF! I suspect I've had fake LM3886's and a short lived CS8412 all in kits from china and my green dac from Analogue metric has some very dubious looking nichicon fine gold smoothers!!!
Never buy caps direct from china, its just far too easy to print heatshrink and sell ant thing on as "For Audio" etc. I suspect that the heatsrhink is on the wrong way round and you've connected that cap in reverse. You should remove the other caps and check the markings on the solder tags to see if the wrapper was the right way round.

Comparing his pics with the other online pics of the cap it looks like it was on correctly. The negative side printing is on the side by the lead with the black marking.
Could have very well been assembled incorrectly if they were hand made by tired workers who just don't give a ****. I doubt they even get tested after assembly.
I found a difference in the position of the diodes D25SBA80. The image on the left of the seller Minishow0328 is inverted in relation to the right, Zoe Tsang Store.
But the observation of the price of U.S. $ 8 dollars for a unit is an indication that it is counterfeit product.
Incidentally, I asked the store once and his response was:
" Dear Friend,
Sorry for the late reply we are busy in this period to the Christmas and New Year is coming. We do not care about any comments in diyaudio.com forum, we have very bad reputations HAD there, but it does not Affect our customers continuous support. Also, we believe the forum is not the biggest forum in the audio world.
Please return the capacitor to the Following address with Economic airmail. We must send you back the correct voltage and similar capacitances (promised Smaller variations). Do not worry for it, all of our customers are satified with our services.
