JTA28H-JTN28H series

Gas discharge tubes (GDT) use noble gasses enclosedin ceramic tubes to provide an alternate circuit path forvoltage spikes.The ceramic envelope and with nickelconnectors allow for high loads and JDT offers products that function at 20KA, 40KA, 50KA, 60KA, 100KA &150KA. The breakdown voltages of the devices have a wide range (up to 20% tolerance).Major applications are high frequency telecommunication lines,stations,security systems,HID and high quality Surge Protection Devices (SPD).

  • Brand： JDT FUSE
  • Classification： gas diacharge tube
  • Voltage： 70-800V
  • Current： 10KA
