GS4B0256R0JDT Description

The GS4B0256R0JDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable resistance values under varying thermal conditions. Built with thin-film technology on a ceramic substrate, it offers a 56Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±0.5%, ensuring consistent performance in matched circuits. The device operates over a wide temperature range (-70°C to +125°C) with a low temperature coefficient of ±50ppm/°C, minimizing resistance drift. Its 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for low-power, high-voltage environments. The gull-wing termination and surface-mount design facilitate automated assembly, while the compact SOIC package (4.9mm x 5.99mm x 1.45mm) saves board space.
