| Features Superior protection at a low price Patented Switch-Grade Fail-Short Device Quick response and high energy handling Low capacitance (<2.5 pF) - ideal for high-speed networks in high exposure environments C UL US LISTED per UL497 (File E53117) (R) Meets test requirements of Telcordia GR 974, GR1361, SBC SR 5165 and RUS PE-80 Solid brass, gold plated pins Test point access option Sealed option for harsh environments 2420 Series 5-Pin Gas Discharge Tube (GDT) Protector The 2420 overvoltage protection modules utilize Bourns' propietary high-efficiency gas discharge tube with our patented Switch-Grade Fail-Short mechanism to provide robust and reliable surge and thermal overload protection at a very competitive price. The 2420 Series is based on Bourns' three-terminal common chamber GDT. This design provides greatly improved and balanced turn-on characteristics for overvoltage protection.The GDT is UL approved for use without a back-up device. Air back-up devices can become contaminated; the circuitry of the 2420 eliminates this possibility. Our unique Switch-Grade Fail-Short device provides more reliable thermal overload protection compared to commonly used solder pellet or insulation burn-through designs. Bourns(R) 2420 Series 5-Pin protectors can be used universally for broadband voice and data circuits including ADSL, ADSL2+, VDSL ISDN and high-speed Ethernet. The 2420 Series is an economical, reliable and low capacitance choice for overvoltage protection of copper pair circuits. Characteristics Test Methods per UL 497, CSA C22.2, Telcordia GR 974, 1361 and SBC SR 5165.
