Notes :
(1) Suffix " B " indicates ± 5% tolerance, suffix " A " indicates ± 10% tolerance.
(2) The surge current (I
ZSM
) is specified as the maximum peak of a non- recurrent half-sin wave of 8.3 ms duration.
(3) Voltage regulation (V
Z
) is the difference between the voltage measured at 10% and 50% of I
