Ever wondered what would happen if the LED circuit failed in an LED lamp, resulting in the main smoothing electrolytic receiving 330V instead of 50V? Then wonder no more..... Clue. Top temperature achieved was 178C on the outside of the electrolytic's case.

Where is the moment where the capacitor vented? Clickbait, yoy are showing the aftermaths.
Thanks for the video =)
basically the leds went open circuit then the capacitor shot up to 340 ish volts causing the other capacitor to go bang
I have once removed an unused electrolytic capacitor from its case, AFAIR 1000µF 35V (it was useless anyway, one of the legs was broken off). I just needed the little aluminium cup for something. The inside part from the capacitor was forgotten lying on a plastic (ABS) case. Few days later, i have discovered that the plastic under the capacitor remnants had "melted" or dissolved, just like with acetone. I wonder what is the composition of electrolyte.
MEGAFART! 😀
the bob ross of electronics
blow up some on camera??
clive! it is amazing for me as I like your videos. how many I miss somehow?
big Clive your the best on YouTube
what only 9. dislikes wow
They also "pweeep"
This was very interesting indeed.
Knowing that those low-voltage electrolytics most likely goes fizz instead of bang in that sort of arrangement is very good to know.
Very educational as well. I'd have thought there be at least a couple of decimetres of ridiculously thin foil in one of those.
This is one of the reasons your channel is my favourite YouTube channel – I often learn something new and listening to a gentle Scottish giant talk about electronics can be almost hypnotic at times.
I wonder if the cap has been intentionally mislabeled so as to protect some of the proprietary info from other Chinese cheaper fly by night manufactures although these parts could be removed and checked for values using a capacitance analyzer.
I'm quite surprised that nobody pointed out the fact that he said "The slight niggle" or at least what it sounded like, and tried to claim he's racist. I'm proud of you youtube. I'm proud of you. We finally made it past those days.
I have to mention this.. Back in my YTS Electronics days in the early 90's I experienced my first electrolytic cap failure. We were making power supplies and a buddy asked me to watch over his while he went to the loo. Folks had a habit of nicking things back then if you werent looking. So i sat doing my work with this guys project sat next to me, I never thought to look at it while it was powered up, checking voltages and stuff. I left it for a bit and after about 5 minutes I heard this hissing sound and before I could react the fat 1000uF cap literally took off and launched up to the roof like a rocket.It made a little thump sound on the metal ceiling, It was so funny but the supervisor thought I was pissing about and it took some explaining to calm him down LOL It turned out the cap was in the wrong way round.
this happen in a far quicker way to me last week with one of those bangood bulkhead lights. first it made all the LEDs go pop and ping till the all went out, then it went bang and boom as the capacitor blew itself to iti witi little pieces. now I know why, thanks.
Full points for knowing when to skip a boring video, Clive. 10+ thumbs-up (if I could).
