SMP 1.25 Surge Withstand Ratings
SMP Surface Mount Power Cross Protection 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 lightning in accordance with the attached table. SMP 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). SMP Fuse are used in circuits to obtain compliance with the test requirements specified in UL 1950/60950 and Bellcore GR 1089.
