Gas discharge Tubes (GDT) are classical components for

protecting the installations of the telecommunications. It is

essential that IT and telecommunications systems -with their

high-grade but sensitive electronic circuits - be protected by

arresters.

The 1812 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 500A

pulse in a miniature package 1812 without destruction.
