TE Circuit Protection 5mm 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.
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:
•
Compact, small form factor suitable for efficient
assembly
•
Helps provide overvoltage fault protection against
high energy surges
•
Suitable for high-frequency applications
Features:
•
3Pole, 5mm 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
