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:

 2Pole, 8mm devices

 Helps provide overvoltage fault protection against

high energy surges

 Broad voltage range from 75V-350V

 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

- Surge protectors

- MDF modules, xDSL equipment, RF system

protection, antenna, base station

- Alarm system
