Gas Discharge Tubes
GTCX28-XXXM-R20 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.
Features:
Benefits:
