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 2 r 0 7 5 - 5 series dc line voltage dimensions 1 of 2 www.sunmate.tw features applications rohs & hf compliant smd structure dc spark-over voltage: 75~1000v low capacitance agency recognition : ul/ cul operating temperature:-30c ~ +85c storage temperature:-40c ~ +115c cable modem xdsl set-top box tv sets power supplier consumer electronics ! ! ! ! ! ! ! ! ! ! ! ! ! 2r-5s series surface mount gas discharge tubes
