Notes:
(2)
The rated discharge current is the total current equally divided between each line to ground and operation(s) are performed in both
polarities. The polarity of lightning surge tests should be reversed between consecutive surges.
(3)
Per IEC 61643-21.
• At delivery AQL 0.65 Level II, DIN ISO 2859.
• Bourns recommends reflowing surface mount devices per IPC/JEDEC J-STD-020 rev D.
