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 across Tip and Ring is undesirable.

These devices are extremely robust and are able to

divert a 1000A pulse without destruction.
