CG4 Series high voltage miniature SMT gas discharge tubes provide high levels of protection against fast rising transients caused by lightning disturbances. These GDTs are high voltage (800V - 3000V) devices designed for over-voltage protection for high isolation applications.

Features:

  • High DC breakdown voltage 800V to 3000 V
  • Surface mount form factor with two squared terminals
  • Medium surge capability 3kA (8/20µs)
  • Miniature footprint
  • Lead-free and RoHS compliant
  • UL Recognized

Applications:

  • Air conditioning
  • Variable frequency drives (VFDs) / inverters
  • High voltage power supply
  • Medical electronics such as X-ray machines and NMR equipment
  • Set-top boxes
  • High voltage test  equipment
