Available in surface-mount packaging, Lumex says it's new family of gas tube arrestors are among the smallest available in the industry. The new GT-SMD1812 series, which measures 4.50-by-3.20mm, provides the same high-performance surge and spike protection as conventional gas tube arrestors, but in a small surface-mount package.

The new surface mount gas tube arrestors are suitable for a wide range of circuit protection applications, including central office or PBX telephone circuits, voice and data lines, solid-state circuitry, or anywhere protection against electrostatic discharge (ESD) or switching surges is needed.

The GT-SMD1812 series is available with DC breakdown voltage ratings of 150-, 200-, 300-, 350- and 400Vdc (with a slew rate of 100V/s). Each device is offered with either 1,000A or 2,000A impulse current ratings.

These hermetically sealed units are UL listed under file # E245199, have an insulation resistance of 104 M? (min) and feature an inter-electrode capacitance of 1pF (max) for minimal disturbance of high frequency or high-impedance data lines.

Supplied in quantities of 500 pieces on standard 12mm wide tape, the company said the unique flat-top packaging of these devices makes them much easier to pick-and-place than conventional round-top units. Additional information can be found online.

Pricing varies depending on model selected and quantity desired. For the standard 150V/1,000A unit, pricing is approximately 70 cents each in quantities of 10,000. Samples are available from stock with production quantities available in six to eight weeks.
