Explosive capacitor

  1. Mar 13, 2008 #1
    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:
