| 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: * Helps provide overvoltage fault protection against high energy surges * Suitable for high-frequency applications Features: * 2Pole, 8mm devices * Broad voltage range from 75V-600V * 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 - MDF modules, xDSL equipment, RF system protection, antenna, base station * Industrial and consumer electronics, such as - Surge protectors - Alarm system Gas Discharge Tubes (c) 2009 Tyco Electronics Corporation.
