SMP Series Fuse
Description
SMP Surface mount Power Cross Protection Fuses are
primarily intended for use in telecommunication circuit
applications requiring low current protection with high surge
tolerance.
These fuses will withstand transient surge currents
generated by lightning in accordance with the attached
table.
SMP fuse 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 intended for use in circuits which require
compliance with the test requirements specified in UL/IEC
1950/60950 and Telcordia GR 1089, Issue 3.
