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/μs to 1kV/μs 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. Littelfuse CG5 MS mini surge arresters are specifically designed for protection of electrical and communication equipment against over voltage transients in surface mount assembly applications. This series offers the most cutting edge protection using non-radioactive elements. ## ~~**Features**~~ - RoHS compliant and Lead-free - Ultra small devices 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 - 5KA surge capability • Conforms to ITU-T K12, tested with 8/20μS IEC 61000-4-5, 2nd pulse as defined by IEC edition 61000-4-5, 2nd edition ## ~~**Applications** Lo~~ - Communication • Broadband equipment equipment • ADSL equipment, - • CATV equipment including ADSL2+ - CATV equipment - XDSL equipment - Test equipment - Satellite and CATV equipment - Data lines - Power supplies - General telecom equipment - Telecom SLIC protection © 2017 Littelfuse, Inc.
