SE Series GDTs (Gas Discharge Tubes) 1206 Size

Littelfuse's new SE Series Gas Discharge Tube (GDT) devices are the smallest GDTs available on the market

Littelfuse SE series GDT offers high surge ratings in a miniature package. It is designed for surface mounting on PCB with small size of 3.2 x 1.6 x 1.6mm. Low insertion loss is perfectly suited to broadband equipment applications. The capacitance does not vary with voltage, and will not cause operational problems with ADSL2+, where capacitance variation across Tip and Ring is undesirable. These devices are extremely robust and are able to divert a 500 A-600 A pulse in a miniature package 1206 without destruction.

  • RoHS compliant and Lead-free
  • GHz working frequency
  • Excellent stability on multiple-pulse duty cycle
  • Excellent response to fast rising transients.
