Raychem Circuit Protection 6mm 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.
Raychem 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 regulato ry standa rds.
Benefits:
• Compact, small form factor suitable for efficient
assembly
• Helps provide overvoltage fa ult protection against
high energy surges
• Suitable for high-frequenc y applications
Features:
• 2Pole, 6mm devices
• Broad voltage range from 75V-600V
• Various form factors: surface mount, axial leads, no
leads
• Low capacitance and inserti on 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
