GS8B031781FBT Description

The GS8B031781FBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 16-pin narrow SOIC package, this bussed (BUS) configuration integrates 15 thin-film resistors, each with a 1.78KΩ resistance and a tight ±1% absolute tolerance. The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±25ppm/°C, ensuring stable performance under thermal stress. With a power rating of 0.8W (0.05W per resistor) and a maximum voltage rating of 100V, it is engineered for reliability in precision circuits. The SOIC-C series construction features gull-wing terminations for robust surface-mount assembly, while its compact dimensions (9.91mm x 5.99mm x 1.45mm) make it suitable for space-constrained designs.
