networking equipment and lines, GDTs protect from
damage that may result from lightning strikes and
equipment switching operations. Features:

  • RoHS compliant
  • Low insertion loss
  • Excellent response to fast rising transients
  • Ultra low capacitance
  • 10KA (A suf?x devices) / 20KA (B suf?x devices) surge capability tested with 8/20?s pulse as de?ned by IEC61000-4-5
  • Available with thermal failsafe option (add ‘F’ suf?x to part number)
