Littelfuse SG Series Gas Discharge Tubes

Littelfuse SG Series Gas Discharge Tubes

Littelfuse SG Series Gas Discharge Tubes (GDT) offer high surge ratings in a miniature package. They are designed for surface mounting on PCB with a small size of 4.5x3.2x2.7mm. The GDTs' low insertion loss is perfectly suited to broadband equipment applications. Their capacitance does not vary with voltage, and will not cause operational problems with ADSL2+, where capacitance variation across Tip and Ring is undesirable. Littelfuse SG Series Gas Discharge Tubes are extremely robust and are able to divert a 1000A pulse without destruction.
