Gas Discharge Tubes GTCX28-XXXM-R05 Series Raychem Circuit Protection Products 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. Raychem Circuit Protection Products 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: • Helps provide overvoltage fault protection against high energy surges • 2Pole, 8mm devices • 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 - MDF modules, xDSL equipment, RF system - Surge protectors protection, antenna, base station - Alarm system Gas Discharge Tubes © 2009 Tyco Electronics Corporation.
