EOL Last Buy Date is January 31, 2021 Type RJS Telecom-Power Cross Protection & Ballast Protection RJS Series RoHS Compliant Description RJS Fuses are primarily intended for use in telecommunication circuit applications requiring low current protection with high surge tolerance. They are typically used to replace heat coil type devices. They are designed to be placed between the line input and the surge arresting components (mov. gas tube, zenor diode, air gaps, etc.) These fuses will withstand transient surge currents generated by lighting in accordance with the attached table. RJS fuses guard protected circuitry against sustained overload or short circuit conditions. Such sustained overloads may be generated by accidental contact between utility cables and phone lines (power line cross). RJS Fuse are primarily designed for use in telecommunications circuits which require compliance with the test requirements specified in UL/IEC 1950/60950 and Telcordia GR 1089, Issue 3 Features - Radial lead surge resistant slow blow fuse - Meet UL 60950 power cross requirements - Designed for compliance with Telcordia GR-1089-CORE - Designed to serve the requirements of a wide range of telecommunication and networking equipment - RoHS 2 compliant - Halogen Free - Lead Free Applications - Fax machines - Answering machines - Telecommunication circuit LEAD FREE = - Ballast protection HALOGEN FREE = Physical Specifications Body : Glass Materials Leads : Matte Tin Plated Copper, Diameter 0.032 On Fuse : bel, RJS, Current Rating, Voltage Rating, Appropriate Safety Logos, RoHS 2 compliant Marking On Label : be,RJS,Current Ratin,Voltage Ratin,Interrupting Ratin, Appropriate Safety Logo and , (China RoHS compliant).
