GS4A031822CT Description

The GS4A031822CT 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 resistance value of 18.2 kΩ and an ultra-tight tolerance of ±0.25%. The network operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±25 ppm/°C, ensuring stability in fluctuating thermal conditions. Encased in a rectangular ceramic SOIC package, it offers excellent power dissipation (0.1W per resistor, 0.4W total) and a maximum voltage rating of 100V. Its gull-wing termination and 1.27mm terminal pitch facilitate easy surface-mount assembly.
