RJSD0303

This is the description about RJSD0303 of the Telecom - Power Cross Protection & Ballast Protection. 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 designedto 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 lightning 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 Fuses are used in circuits to obtain compliance with the test requirements specified in UL 1950/60950 and Bellcore GR 1089.

These are the RJSD0303 environmental specification. Soldering techniques and compatibility: Wave Solder is 260°C, 10 sec max, (MIL-STD-202, method 210).
