Gas Discharge Tubes
GTCX26-XXXM-R05 Series
TE Circuit Protection 6mm 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.
TE 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.
Benefits:
Features:
Compact, small form factor suitable for efficient
2Pole, 6mm devices
assembly
Broad voltage range from 75V-600V
Helps provide overvoltage fault protection against
Various form factors: surface mount, axial leads, no
high energy surges
leads
Suitable for high-frequency applications
Low capacitance and insertion loss
UL 497B recognized
RoHS compliant
Devices tested per ITU K.12 recommendations
Non-radioactive materials
Applications:
Telecommunications Industrial and consumer electronics, such as
- MDF modules, xDSL equipment, RF system - Surge protectors
protection, antenna, base station - Alarm system
