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 reï¬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 >108 Ω (-25 %, +30 % for Models 2027-07-SM, 2027â09-SM and 2027â60-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.
Speciï¬cations are subject to change without notice.
Customers should verify actual device performance in their speciï¬c applications.
