My experience is that the only time electrolytic caps explode is either when the polarity is backwards or when a rectifier diode fails and AC appears across them. I've found other age-related failures to generally be more benign. Generally they just lose their capacitance but don't start conducting. Now tantalum caps are another story. They almost always fail by short circuiting, sometimes catching fire. 73, Jim W8ZR _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
