Gas Discharge Tubes GTCX25-XXXM-R02 Series TE Circuit Protection 5mm 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. 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: Features: Compact, small form factor suitable for efficient assembly 2Pole, 5mm devices Broad voltage range from 75V-600V Helps provide overvoltage fault protection against high energy surges Various form factors: surface mount, axial leads, no leads Suitable for high-frequency applications Low capacitance and insertion loss UL 497B recognized RoHS compliant Devices tested per ITU K.12 recommendations Non-radioactive materials Applications: • Industrial and consumer electronics, such as Telecommunications - MDF modules, xDSL equipment, RF system - Surge protectors protection, antenna, base station - Alarm system Gas Discharge Tubes © 2008, 2011 Tyco Electronics Corporation, a TE Connectivity Ltd.
