Gas Discharge Tubes(GDT)
2RD-8 Series
Description
GDT is placed in front of, and in parallel with, sensitive telecom
equipment such as power lines, communication lines, signal
lines and data transmission lines to help protect them from
damage caused by transient surge voltages that may result from
lightning strikes and equipment switching operations. These
devices do not influence the signal in normal operation.
However, in the event of an overvoltage surge, such as a
lightning strike, the GDT switches to a low impedance state and
diverts the energy away from the sensitive equipment.
Our GDT offer a high level of surge protection, a broad voltage
range, low capacitance, and many form factors including new
surface mount devices, which makes them suitable for
applications such as Main Distribution Frame (MDF) modules,
high data-rate telecom applications (e.g. ADSL, VDSL), and
surge protection on power lines. Their low capacitance also
results in less signal distortion. When used in a coordinated
circuit protection solution with PolySwitch devices, they can help
equipment manufacturers meet stringent safety regulatory
standards.
