Littelfuse Circuit Protection 5mm 3Pole GDTs (ceramic
gas discharge tubes), are commonly used to help
protect sensitive telecom equipment such as
communication lines, signal lines and data transmission
lines from damage caused by transient surge voltages
that typically result from lightning strikes and equipment
switching operations.
Littelfuse Circuit Protection GDTs offer a high level of
surge protection, low capacitance and a broad array of
breakover voltage levels, making them suitable for
applications such as MDF (Main Distribution Frame)
modules, high data-rate telecom applications (e.g.
ADSL, VDSL), and surge protection on power lines.
Littelfuse Circuit Protection GDTs can help equipment
meet the most stringent regulatory standards.
