SG Series
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.
