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 • RoHS compliant and • Ultra small devices Lead-free offered in a variety of Agency Agency File Number • GHz working frequency mounting lead forms E128662 • Excellent stability on • Non-Radioactive multiple pulse duty cycle • Low capacitance (<1pF) • Excellent response to • Voltage Ranges 75V to 2 Electrode GDT Graphical Symbol fast rising transients. 600V • Ultra Low Insertion Loss • UL Recongized • 1-2KA surge capability • Conforms to ITU-T K12, tested with 8/20μS IEC 61000-4-5 pulse as defined by IEC • Square Outline 61000-4-5 Additional Information Applications • Communication • Broadband equipment equipment • ADSL equipment, Datasheet Resources SSaammpplleess • CATV equipment including ADSL2+ • Test equipment • XDSL equipment • Data lines • Satellite and CATV equipment • Power supplies • General telecom • Telecom SLIC equipment protection © 2020 Littelfuse, Inc.
