Product Description

 

1206 Surface Mount 2-Electrode Squared Ceramic Gas Discharge Tube GDT 3216 350V 500A 3.2x1.6x1.6mm Non-radioactive

 

 

Description

 

1)Are classical components for protecting installations of telecommunications
2)Essential that IT and telecommunications systems, with their high-grade but sensitive electronic circuits, be protected by arresters
3)1206 series GDT offers high surge ratings in miniature package
4)Designed for surface mounting on PCB with small size 3.2x1.6x1.6mm
5)Low insertion loss is perfectly suitable to broadband equipment applications
6)Capacitance don't vary with voltage and will not cause operational problems with ADSL2+, where capacitance variation across tip and ring is undesirable
7)These devices are extremely robust and are able to divert 500A pulse in miniature package 1206 without destruction
