SG Series Gas Discharge Tubes SG Series RoHS Agency Approvals AGENCY AGENCY FILE NUMBER E128662 2 Electrode GDT Graphical Symbol Additional Information Datasheet Resources Samples Description Littelfuse SG series GDT offers high surge ratings in a miniature package. It’s designed for surface mounting on PCB with small size 4.5x3.2x2.7mm. 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 1000A pulse without destruction.
