General Characteristics
Part Marking
(1) Disk Diameter
(2) Type
(3) Varistor Voltage
(4) Tolerance
(5) N = RoHs Compliant Series (as of October 2007 forward, per Date Code)
(6) B = Phenolic coating rated at 500 VDC. Phenolic coating rated at 2000 VDC requires no marking.
Date Code
528 = First digit represents year (5 = 2005). Second and third digits represent the week of the year.
This new date code system was implemented from 9/15/05.
