GS4A023091CT Description

The GS4A023091CT 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 resistance value of 3.09 kΩ and an ultra-tight ±0.25% tolerance. The device operates over a wide temperature range of 70°C to 125°C with a derated power rating, ensuring reliability in thermally challenging environments. Its ±50 ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision circuits. The SOIC-C series construction offers robust ceramic substrate durability, while the gull-wing termination facilitates reliable surface-mount assembly.
