Product Details

Gas Discharge Tubes - GTCX37-XXXM-R10 Series

GTCX37-XXXM-R10 Series Circuit Protection 7mm 3Pole 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.

GTCX37 series offers 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.
Broad voltage range from 75V-600V
Various form factors: surface-mount, leaded, no leads
Optional fail-short mechanism on some devices
Low capacitance and insertion loss
Crowbar overvoltage protection


Telecommunications - MDF modules, xDSL equipment, RF system protection, antenna and base station
Industrial and consumer electronics, such as Surge protectors and Alarm systems
