Littelfuse GTCA26-900M-R05-2

Littelfuse gas discharge tubes are connected in parallel at the front end of sensitive telecommunications equipment (such as power lines, communication lines, signal lines, and data transmission lines) to help protect these devices from damage caused by transient surge voltages resulting from lightning strikes and equipment switching operations. These devices do not affect signals during normal operation. However, when an overvoltage surge occurs (such as a lightning strike), the gas discharge tube switches to a low-impedance state and diverts energy away from the sensitive equipment. Our gas discharge tubes offer high-level surge protection, wide voltage range, low capacitance, and a variety of package sizes (including new SMT devices), making them suitable for main distribution frame modules, high data rate telecommunications applications (e.g., ADSL, VDSL), and surge protection on power lines. Their low capacitance characteristic also reduces signal distortion. When used with PolySwitch devices in a coordinated circuit protection scheme, they can help equipment manufacturers meet stringent safety regulatory standards.
