GS4A031203GBT Description

The GS4A031203GBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 120KΩ resistance and a tight ±2% absolute tolerance. The device operates within a temperature range of 70°C to 125°C, delivering a 0.1W power rating per resistor (0.4W total). Its ±25ppm/°C temperature coefficient ensures stability in varying thermal conditions, while the 100V maximum voltage rating and gull-wing termination make it suitable for surface-mount PCB designs.
