GS8B031741DDT Description

The GS8B031741DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. Housed in a 16-pin narrow SOIC package, this bussed network integrates 15 thin-film resistors, each with a resistance value of 1.74KΩ and an absolute tolerance of ±0.5%. The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient (TCR) of ±25ppm/°C, ensuring minimal resistance drift. Its SOIC-C series construction offers a compact footprint (9.91mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. Rated for 100V maximum voltage and 0.8W total power dissipation, it is ideal for precision analog and digital circuits.
