Gas Discharge Tubes GTCS23-XXXM-R01-2 Series Littelfuse Circuit Protection 3mm 2Pole SMD type 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 3mm SMD type GDTs offer excellent surge protection characteristics, low capacitance and a broad array of breakover voltage levels, making them suitable for applications such as high data-rate telecom communication network protection (e.g. ADSL, VDSL). Benefits: Features: Compact, small form factor suitable for efficient assembly 2Poles, 3mm devices Broad voltage range from 75V-400V Suitable for high-frequency applications Form factor: surface mount Low capacitance and insertion loss Rerfering to ITUT K.20 and ITUT K.21 UL 497B recognized RoHS compliant Devices tested per ITU K.12 recommendations Non-radioactive materials Applications: Telecommunications, RF system protection, CATV Modem, Hub protection, Security Systems, Data acquisition (c) 2016 Littelfuse,Inc Specifications are subject to change without notice .
