GS4B031021BAT Description

The GS4B031021BAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC (SOIC-C series) device integrates 7 bussed resistors with a 1.02KΩ resistance value, offering an absolute tolerance of ±0.1% and a ratio tolerance of ±0.05%. Built with thin-film technology, it ensures excellent stability and low noise, making it ideal for precision circuits. The ±25ppm/°C temperature coefficient and 0.4W total power rating (0.05W per resistor) enable reliable performance across a 70°C to 125°C operating range. Its 100V maximum voltage rating and surface-mount gull-wing termination suit compact, high-density PCB designs.
