SG Series

Description

Littelfuse SG series GDT offers high surge ratings

in a miniature package. It’s designed for surface

mounting on PCB with small size 4.5x3.2x2.7mm.

Low insertion loss is perfectly suited to broadband

equipment applications. The capacitance does not vary

with voltage, and will not cause operational problems

with ADSL2+, where capacitance variation acrossTip

and Ring is undesirable. These devices are extremely

robust and are able to divert a 1000A pulse without

destruction.
