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) ■ ■ ■ ■ 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® 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.
