Series - Multi-Stage Protector Sub-Assembly
Bourns MSP
®
Series is a new generation of telecommunications protector designed to be the best all-around protection choice on both today
and tomorrow’s copper pair based communications circuits. It combines the strengths of gas tube and solid-state protectors while eliminating
their weaknesses. Bourns’ new MSP
®
protector series is the synergistic integration of three advanced protection technologies; sixth generation
gas tube, precision matched MOVs, and switch-grade failshort. Working together, these three technologies meet the challenges of the evolv-
ing high-speed network.
Bourns MSP
®
Series can be used universally on POTS, ISDN, ADSL, SDSL, HDSL, RADSL, VDSL, 10BaseT, and T1 carrier. Bourns MSP
®
Series is the most economical, reliable, and best performing choice for all paired copper communications circuits.
