Notes:

  • UL Recognized component, UL File E153537
  • 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.
  • Sparkover limits after life ±20 % (-25 %, +30 % for Model 2035-09, 2035-60), IR >10
  • At delivery AQL 0.65 Level II, DIN ISO 2859.
  • Bourns recommends refl owing surface mount devices per IPC/JEDEC J-STD-020 rev D. (2) Network applied. (3) Tube may exceed ±20 % but will continue to protect without venting.
