GS8B031871GDT Description

The GS8B031871GDT 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 1.87 kΩ resistance and a tight ±2% absolute tolerance. The device operates over a wide temperature range (70°C to 125°C) with a low ±25 ppm/°C temperature coefficient, ensuring stable performance under thermal stress. Its 0.05W (1/20) power rating per resistor and 0.8W total power rating make it suitable for low-power circuits, while the 100V maximum voltage rating adds robustness. The SOIC-C series construction features gull-wing terminations for reliable surface-mount assembly, with precise dimensional tolerances (±0.1mm height, ±0.2mm depth).
