SG400

Gas Discharge Tubes SG Series SG Series RoHS 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. Features Agency Approvals Agency • RoHS compliant and Lead-free • GHz working frequency • Excellent stability on multiple pulse duty cycle • Excellent response to fast rising transients. • Ultra Low Insertion Loss • 1-2KA surge capability tested with 8/20μS pulse as defined by IEC 61000-4-5 Agency File Number E128662 2 Electrode GDT Graphical Symbol Additional Information Applications • Communication Datasheet Resources • Ultra small devices offered in a variety of mounting lead forms • Non-Radioactive • Low capacitance (1GΩ (at 50VDC) >1GΩ (at 100VDC) >1GΩ (at 50VDC) 2A ~10 V ~1.0 A 2.5 A >1GΩ (at 100VDC) 2A ~12 V ~0.5 A ~90 V ~20 V ~0.8 A ~140 V NA* ~90 V 2A ~140 V NA* ~90 V 2A ~12 V ~0.5 A ~10 V
