GS8B034321FBT Description

The GS8B034321FBT 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 4.32KΩ resistance and a tight ±1% absolute tolerance. The device operates over a wide temperature range (-70°C to +125°C) with a low ±25ppm/°C temperature coefficient, ensuring stability in harsh environments. 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 features gull-wing terminations for reliable surface-mount (SMD) assembly, while the ceramic case enhances thermal and mechanical durability.
