GS4A032210CT

GS4A032210CT Description

The GS4A032210CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 221Ω resistance and an ultra-tight ±0.25% tolerance. The device operates within a wide temperature range of 70°C to 125°C (derated) and delivers a 0.1W power rating per resistor (0.4W total). Its ±25ppm/°C temperature coefficient ensures minimal resistance drift, making it ideal for precision circuits. The SOIC-cased network supports surface-mount (SMD) assembly with gull-wing terminations and a 1.27mm terminal pitch, facilitating compact PCB layouts.
