SMT fuse for telecom applications

29 January 2003 Circuit & System Protection

Bel Fuse has released a surface mount, power cross protection fuse. Developed to ensure compliance with the Power Cross test requirements UL 1950/60950 and Bellcore/Telcordia GR-1089 for Tip and Ring protection, the device further withstands lightning surges specified in FCC 47 Part 68.

The Bel Fuse SMP fuse is specifically designed for lightning surge withstand and power cross protection of telecom circuits requiring low current protection with high surge tolerance, eg, use in ISDN and analog telephones, fax machines, modems, answering machines, switching line cards, line test equipment and PBX equipment. It may additionally be specified for use in a wide range of DSL, general purpose and primary and ballast protection applications.

Measuring 9,65 x 3 mm (l x h), the component's surface mount package provides significant PCB real estate savings over conventional axial leaded glass fuses, maximises manufacturing throughput, and reduces OEM costs.
