Littelfuse Circuit Protection 8mm 2Pole 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.
