Exploding capacitor video
Nov 06, 2009, 12:41 am
This short video shows the results of two electrolytics and a tantalum capacitor with reversed polarity and modest voltage overage. The 10 uf tantalum cap not only explodes but burns very nicely afterward. One of the electrolytics manages a really ferocious bang but, to be fair, it's 470uf.
He's running 15V reversed into 10v caps but I bet that's not the important factor.

Excellent, all beginners should see this.
This is why using tantalum capacitors in a power supply or for supply decoupling is not a good idea. Even when they are connected the right way round they can fail short circuit and burn like that.

"I know! Lets blow some **** up!"
this guy is funny.
That is such a hilarious line.
And I learned something, too!:
don't connect caps the wrong way at 5v higher than they should be.
Great advice!!!

Haha!
"Here's a cap without a vent on top! Is that gonna f*** us?"
At least, that's what I thought I heard. :-)

We used to do this in college lab classes. Shoot them off the breadboard and into the celing.

More like 14 volts too much
He clearly says at the end that you shouldn't go past a volt or a volt and a half when wiring em up backwards =P

That guy is rather energetic, isn't he?
The tant cap was interesting to watch. You get an explosion, and then "oh look, it's on fire."
Then a few seconds of not much action.
Then, suddenly, "oh DANG! It's REALLY on fire!"
