Compact fuse helps meet US telecomms specs

The new Raychem FT600 fuse series is designed to assist telecomms equipment manufacturers in complying with North American overcurrent protection requirements.

The new Raychem FT600 fuse series is designed to assist telecomms equipment manufacturers in complying with North American overcurrent protection requirements, including Telcordia GR-1089, FCC Part 68, and UL60950 3rd edition.

In some circuit designs the preferred PolySwitch PPTC device solution may not be ideal, such as on height-constrained, high-density line cards.

In these applications, the low profile and small footprint of the FT600 fuse provide a practical overcurrent protection solution.

The device offers low temperature-rise performance under sneak current fault events to prevent damage to circuit traces or multilayer boards, and when used in conjunction with a SiBar thyristor device, helps designers comply with regulatory standards.

The FT600 series includes devices rated for maximum operating currents of 1.25, 0.500 and 2.0A, and is suitable for ambient temperatures up to 85C.

"This FT600 fuse series was developed in response to customer requests for a low-profile overcurrent protection device that could be used in high-density or space-constrained applications", said Rodrigo Rubiano, Telecommunications and Networking Market Manager for Raychem Circuit Protection.

"This device expands the range of circuit protection options we can offer to our customers and helps them comply with industry regulations", he added.

The FT600 fuse is available in tape and reel packaging for compatibility with high-volume manufacturing.
