Micro-Gap Design 11.5mmx7.5mm Sized Gas Discharge Tube GDT
SE72-600X 600V 20KA 3PIN For Cable Modem
GDT introduction
Gas discharge tubes (GDT) use noble gasses enclosed in ceramic
tubes to provide an alternate circuit path for voltage spikes.The
ceramic envelope and with nickel connectors allow for high loads
and Surging offers products that function at
20KA,40KA,50KA,60KA,100KA&150KA. The breakdown voltages of the
devices have a wide range (up to 20% tolerance).Major applications
are high frequency telecommunication lines,stations, security
systems,HID and high quality Surge Protection Devices (SPD).

Telcome Network Application
In Internet communication system, modem equipment, router,
switch,hub,network card ,UPS,monitoring equipment, mobile
communication,base station and antenna are more likely to be
damaged by the over voltage. Shaoxin Electronics successfully apply
the lighting protection and anti-static functions of electronic
components to the Internet communication equipment and avoid the
influence on communication quality.
Auto Electronics Application
As the smart car collision avoidance system, Intelligent cruise
system, automatic parking system,autopilot and car network
technology system are widely used in the modern car
,electronization and intellectualization is become the sign and
trend . Shaoxin Electronic will provide the customer with the
ceramic gas discharge tube, transient voltage suppressor and ESD
suppressor, which are widely used to protect the car electronic
systems.
