a. The maximum continuous voltage is 5.25V. Voltages up to 6.0V for up to 10 seconds, cumulative duration, over
the lifetime of the device are allowed. Voltages as high as 5.5V for up to 250 seconds, cumulative duration, over
the lifetime of the device are allowed.
b. Minimum capacitor value refers to the residual capacitor value after taking into account the part–to–part
tolerance, DC–bias, temperature, and aging.
