GS4A031431FBT Description

The GS4A031431FBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 1.43KΩ and a tight ±1% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in harsh environments. Its ±25ppm/°C temperature coefficient and ±0.1% ratio tolerance make it ideal for precision analog circuits. The SOIC-C series construction provides excellent thermal stability and mechanical robustness, while the gull-wing termination facilitates easy surface-mount assembly.
