Littelfuse, Inc. Littelfuse SG Series GDT SG450Q

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 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 8/20uS pulse as defined by IEC 8100-4-5 Ultra small devices offered in a variety of mounting lead forms Non-Radioactive Low capacitance (<1 pF) Voltage Ranges 75V to 420V UL recognized Conforms to ITU-T K12, IEC 1000-4-5 Square OutlineApplicationsC ommunication equipment CATV equipment Text equipment Data lines Power supplies Telecom SLIC protection Broadband equipment ADSL equipment including ADSL2+ XDSL equipment Satellite and CATV equipment General telecom equipment
