Square Body GDTs from Littelfuse Protect Against Overvoltage Transients, Simplify Pick and Place Process
2017-02-06 | ReturnTypical applications for SH Series Gas Discharge Tubes include G.fast, xDSL, 10GbE, and 10/100/1000 Base-T Ethernet port protection for the telecom/datacom market; coaxial cable protection in satellite, CATV equipment and set top boxes for consumer products; industrial automation interfaces such as Ethernet, RS-485, RS-232, etc. for the industrial market; and AC power line protection in power inverter/Variable Frequency Drives (VFDs) for the renewable energy market.
“The SH Series GDT is an ideal solution because it can meet today’s high surge rating requirements while maintaining compatibility with high speed, wide bandwidth applications,” said Stephen Li, global product manager, Gas Discharge Tubes at Littelfuse. “In addition to protecting electrical, multimedia, and communication equipment against overvoltage transients, it also simplifies the SMT pick and place assembly process due to its square body and terminals.”
SH Series Gas Discharge Tubes offer these key benefits:
。High surge withstand capability in a miniature package makes them ideal for high surge, high density layout applications such as radio base station power and cable modems.
。Low off-state capacitance (≤0.7pF) minimizes insertion loss. Also, this value does not vary as the signal voltage varies, so it does not demodulate the signal of interest. These features make it compatible with high speed, wide bandwidth applications such as G.fast, xDSL equipment, and cable modems.
。The square body and terminals of the SH Series make the pick and place process simpler during automated PCB manufacturing, compared to cylindrical body GDTs.
Availability
SH Series Gas Discharge Tubes are available in tape and reel packaging in quantities of 900. Sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
