CG34.0LTR

The Littelfuse CG34.0LTR is a two-electrode gas discharge tube (GDT) from the CG3 series designed for surge protection and high isolation applications. It provides a typical DC breakdown voltage of 4000V (minimum 3200V, maximum 4800V at 100V/s) and an impulse breakdown voltage of 5800V at 100V/µs and 6000V at 1kV/µs. The device features insulation resistance of 10 GΩ minimum at 100V and a low capacitance of less than 1.5pF at 1MHz, making it suitable for high-speed signal lines. The arc voltage is approximately 25V at 1A. It can handle a nominal impulse discharge current of 5kA (8/20µs) and a maximum surge current of 10kA (8/20µs, single shot). The GDT is housed in a rugged ceramic-metal axial cylinder package with through-hole mounting and axial leads. It is available in tape-and-reel packaging. The part is RoHS3 compliant with MSL 1 unlimited and REACH unaffected status (low confidence, unverified). Typical applications include CRT terminals, CATV equipment, antennas, power supplies, and medical electronics.
