Surge Suppressor, 185 VDC (Core-Earth) Voltage Rating, 150 mA (Nom.) Current Rating, Black Color

Telecommunications protection with RJ12/RJ45 female connectors can be used internationally for the protection of analog telecommunications interfaces, such as telephones, telefaxes, modems and answering machines with a maximum operating voltage of 185 V.
The D-FM-A/RJ45-BB products are series connected for analog phone lines. The hybrid silicon avalanche diode array and gas discharge tube provides tight clamping voltage line-to-line on each signal pair and high surge current handling capacity line-to-line, line-to-shield and shield-to-ground. The circuit is safely pass ring voltages, while clamping transient voltages. Connection is possible with both RJ11 and RJ12 connections.
