Why electrolytic capacitors blow up
The most common culprit for shortening electrolytic cap life is heat. A capacitor rated for 10,000 h at 25°C will be derated for use in higher temperatures–it may only be rated for 1,000 h at 85°C, even less at 105°C. The heat generally acts to evaporate the electrolyte and reduce the capacitance.
