GS7B031871DBT Description

The GS7B031871DBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 14-pin narrow SOIC package, this bussed (BUS) network integrates 13 thin-film resistors, each with a 1.87 kΩ resistance 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 of ±25 ppm/°C, ensuring stable performance under thermal stress. Its 0.05W (1/20) power rating per resistor and 0.7W total power rating make it suitable for low-power circuits, while the 100V maximum voltage rating adds robustness. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount assembly.
