Gas Discharge Tubes
GTCX25-XXXM-R02 Series
TE Circuit Protection 5mm 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.
Raychem 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. Raychem Circuit
Protection GDTs, can help equipment meet the
most stringent regulatory standards.
