(1)
The deviation parameters VI(dev) and II(dev) are defined as the differences between the maximum and minimum values obtained over
the rated temperature range. For more details on VI(dev) and how it relates to the average temperature coefficient, see Temperature
Coefficient.
(2)
The dynamic impedance is defined by |ZKA| = ΔVKA/ΔIKA. For more details on |ZKA| and how it relates to VKA, see Dynamic
Impedance.
