GS4A031152BT Description

The GS4A031152BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under elevated temperatures. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 11.5 kΩ and an ultra-tight tolerance of ±0.1%. The device operates over a wide temperature range of 70°C to 125°C with a derated power capability, ensuring reliability in thermally challenging environments. Its ±25 ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision analog and digital circuits. The 100V maximum voltage rating and 0.4W total power dissipation further enhance its suitability for industrial and instrumentation applications.
