Descriptions:
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.
