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 re?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.
? Sparkover limits ±20 % after life, IR >10 8 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.
**
***
Network applied.
DC Sparkover may exceed ±20 % after discharge, but will continue to protect without venting.
*RoHS Directive 2002/95/EC Jan 27, 2003 including Annex.
Speci?cations are subject to change without notice.
Customers should verify actual device performance in their speci?c applications.
