Notes:
• UL recognized component, UL File E153537.
• Model number marking on tube: 27-xxxV.
• Surface Mount (SM) parts may show a temporary increase in DCBD after the solder reflow process. Most devices will recover within 24 hours
time. It should be noted that there is no quality defect nor change in protection levels during the temporary change in DCBD.
• Sparkover limits ±20 % after life, IR >108 Ω (-25 %, +30 % for Models 2027-07-SM, 2027–09-SM and 2027–60-SM).
• At delivery AQL 0.65 Level II, DIN ISO 2859.
• Bourns recommends reflowing surface mount devices per IPC/JEDEC J-STD-020 rev D.
