Littelfuse Circuit Protection 3mm 2Pole SMD type
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 3mm SMD type GDTs
offer excellent surge protection characteristics, low
capacitance and a broad array of breakover
voltage levels, making them suitable for
applications such as high data-rate telecom
communication network protection (e.g. ADSL,
VDSL).
Benefits:
Compact, small form factor suitable for efficient
assembly
Suitable for high-frequency applications
Features:
2Poles, 3mm devices
Broad voltage range from 75V-400V
Form factor: surface mount
Low capacitance and insertion loss
Rerfering to ITUT K.20 and ITUT K.21
UL 497B recognized
RoHS compliant
Devices tested per ITU K.12 recommendations
Non-radioactive materials
Applications:
Telecommunications, RF system protection, CATV Modem, Hub protection, Security Systems, Data acquisition
