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 Parameter
Measurement Information.
(2)
The dynamic impedance is defined by |ZKA| = ΔVKA/ΔIKA. For more details on |ZKA| and how it relates to VKA, see Parameter
Measurement Information.
