GS8B034121BT Description

The GS8B034121BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. Housed in a 16-pin narrow SOIC package, it features 15 bussed (BUS) thin-film resistors, each with a 4.12KΩ resistance and an absolute tolerance of ±0.1%. The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±25ppm/°C, ensuring minimal resistance drift. Its 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction offers robust performance in surface-mount applications, with a compact footprint (9.91mm × 5.99mm × 1.45mm) and gull-wing termination for reliable PCB mounting.
