GasDischarge Tubes GTCX28-XXXM-R10 Series TE 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. TE 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: 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 - MDF modules, xDSL equipment, RF system - Surge protectors protection, antenna, base station - Alarm system Telecommunications Industrial and consumer electronics, such as Gas Discharge Tubes Document: SCD27375 Status: Released MDF modules, xDSL equipment, RF sytem 2008, 2011, 2014 Tyco Electronics Corporation. 1 Rev: C Date: SEPTEMBER 29, 2014 a TE Connectivity Ltd.
