Gas Dis charge Tubes
GTCX28-XXXM-R10 Series
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.
Benefits:
Features :
Helps provide overvoltage fault protection against
2Pole, 8mm devices
high energy surges
Broad voltage range from 75V-600V
Suitable for high-frequency applications
Various form factors: surface mount, axial leads, no
leads
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
- Surge protectors
- MDF modules, xDSL equipment, RF system
protection, antenna, base station
- Alarm system
