Gas Discharge Tube (GDT) Products CG5 and SL0902A Series CG5 and SL0902A Series Description Littelfuse Broadband Optimized SL0902A Series offers high surge ratings in a miniature package. Special design features provide high levels of protection against fast rising transients in the 100V/s to 1kV/s range usually caused by lightning disturbances. 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 2500A pulse without destruction. For AC Power Cross of long duration, overcurrent protection is recommended. Agency Approvals Littelfuse CG5 MS mini surge arresters are specifically AGENCY AGENCY FILE NUMBER designed for protection of electrical and communication equipment against over voltage transients in surface E128662 mount assembly applications. This series offers the most cutting edge protection using non-radioactive elements. 2 Electrode GDT Graphical Symbol Features RoHS compliant and Ultra small devices Lead-free offered in a variety of mounting lead forms GHz working frequency Non-Radioactive Excellent stability on multiple pulse duty cycle Low capacitance (<1pF) Excellent response to Voltage Ranges 90V to fast rising transients. 600V Ultra Low Insertion Loss UL recognized 2.5KA surge capability Conforms to ITU-T K12, tested with 8/20S IEC 1000-4-5 pulse as defined by IEC 61000-4-5 Applications Broadband equipment Communication equipment ADSL equipment, including ADSL2+ CATV equipment XDSL equipment Test equipment Satellite and CATV Data lines equipment Power supplies General telecom Telecom SLIC equipment protection 2010 Littelfuse, Inc. 13 CG5 and SL0902A Series Specifications are subject to change without notice.
