1740 Series – Coaxial Surge Protector
75 Ohm Powered & Unpowered Coax DC to >1 GHz
The Bourns 1740 Series of Primary Broadband Coaxial Surge Protectors is designed for Network and other high frequency applications. The 1740 Series provides protection against surges on 75 ohm coax subscriber drops and has a fail-short mechanism in the event of dangerous power-crosses. The protector will pass bi-directional signals over the bandwidth from DC to in excess of 1 Ghz. Its cast-metal housing and environmentally sealed design will withstand the toughest Outside Plant Applications. ■ Reduces cost of network maintenance ■ Listed per 497 C ■ Patent # 5,508,873 (U.S.); #2,169,604 (Canada) Product Dimensions 55.88 (2.20) 81.28 (3.20) 12.70 (.50) 19.05 (.75) Min.
