Fuses for telecom circuits
25 September 2002
Circuit & System Protection
Bourns has introduced a telecom fuse that enhances its substantial circuit protection offering. The model B1250T Telefuse is a powercross protection fuse designed for use in telecommunications circuit applications requiring low current protection with high surge tolerance. The telecom fuse is ideal for protecting Central Office and Customer Premise Equipment, including POTS, T1/E1, ISDN and xDSL circuits.
Model B1250T allows overcurrent compliance with telecom specifications, including Telcordia GR-1089, UL 60950, and ITU K.20 and K.21. When used in conjunction with the Bourns' TISP family of overvoltage protection products, the combination offers a complete protection solution.
