Littelfuse Circuit Protection 6mm 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.
