Gas Discharge Tubes
GTCX38-XXXM-R10 Series
Raychem Circuit Protection 8mm 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.
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.
Benefits:
•
Helps provide overvoltage fault protection against
high energy surges
•
Suitable for high-frequency applications
Features:
•
3Pole, 8mm devices
•
Broad voltage range from 75V-600V
•
Various form factors: surface-mount, leaded, no
leads
•
Optional fail-short mechanism on some devices
•
Low capacitance and insertion loss
•
Crowbar overvoltage protection
•
UL 497B recognized
•
RoHS compliant
•
Devices tested per ITU K.12 recommendations
•
Non-radioactive materials
Applications:
•
Telecommunications
- MDF modules, xDSL equipment, RF system
protection, antenna, base station
•
Industrial and consumer electronics, such as
- Surge protectors
- Alarm system
