storage temperature: -40c ~ +115c gdt introduction:gas discharge tubes (gdt) use noble gasses enclosed in ceramic tubes to provide an alternate circuit path for voltage spikes.the ceramic envelope and with nickel connectors allow for high load s and ruilon offers products that function at 20ka,40ka,50ka,60ka,100ka&150ka. the breakdown voltages of the devices have a wide range (up to 20% tolerance).major applications are high frequency telecommunication lines,stations, security systems,hid and high quality surge protection devices (spd). part number code 3 r 0 7 5 - 8 series dc line voltage dimensions t b lead type t=thrust s=smd electrical characteristics a=5000a b=10000a gas discharge tubes features rugged ceramic-metal construction available with or without leads available with fail-safe clip dc spark-over voltage:75~600v low capacitance agency recognition :ul operating temperature : -30c ~ +85c ! ! ! ! ! ! ! cable modem xdsl set-top box tv sets power supplier consumer electronics ! ! ! ! ! ! t d unit:mm item dimensions spec. tolerance d 8.0 +0.2/-0.8 t 10.0 0.5 applications 3rsb-8 series 1 of 2 www.sunmate.tw
