Notes:
• UL Recognized component, UL File E153537.
• At delivery AQL 0.65 Level II, DIN ISO 2859.
• Surface Mount (SM) parts may show an increase in DCBD after the solder reflow process. There is no quality defect nor a change
in the protection level, even if the DCBD is outside the original tolerance.
