Exploding Polarized Capacitors - Causes and Mechanisms

[DaTario]

Hi All,

I would like to know what makes a polarized capacitor to explode. Too much voltage? Tension in the wrong direction? What is the mechanism behind. I have exploded accidentally one of those capacitors with plastic cover, with 1000 mu farad and 16 V. The voltage I put was 15 V.

thanks in advance

A short causing heating and production of steam, or even electolysis and production of
hydrogen. An old capacitor might short below its rated voltage.

you could have a capacitor affected with this:
