GS4A021803CT

GS4A021803CT Description

The GS4A021803CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 180 kΩ resistance and an exceptional ±0.25% tolerance. Built with a rectangular ceramic SOIC package, it offers superior thermal stability and reliability across a wide temperature range of 70°C to 125°C. The ±50 ppm/°C temperature coefficient ensures minimal resistance drift, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision circuits. The gull-wing termination and 1.27mm terminal pitch facilitate easy surface-mount assembly.
