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
