GS4A021272FAT Description

The GS4A021272FAT 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 12.7KΩ and an absolute tolerance of ±1%. The device operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient (±50ppm/°C), ensuring stable performance under thermal stress. Its SOIC-C series construction offers superior reliability in surface-mount applications, with a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V. The gull-wing termination and ceramic case provide robust mechanical and electrical integrity.
