Description of Driving Event:
Most tantalum capacitors are sensitive to the polarity of the applied voltage. Incorrect installation and/or improper circuit application that subjects the capacitors to reverse bias may lead to performance degradation or catastrophic failure (short circuit) of the capacitor. Dry slug tantalum capacitors can survive being installed backwards for long periods of time (thousands of hours) when derated to 15% or less of rated voltage.
