Model number marking on tube: 27-xxxV. Surface Mount (SM) parts may show a temporary increase in DCBD after the solder refl ow 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. 8 Sparkover limits 20 % after life, IR >10 (-25 %, +30 % for Models 2027-07-SM, 202709-SM and 202760-SM).
