GS4A021271FAT

GS4A021271FAT Description

The GS4A021271FAT 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 1.27KΩ 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 ±50ppm/°C temperature coefficient and ±0.05% ratio tolerance make it ideal for precision analog circuits. The SOIC-C series construction provides excellent thermal stability and low noise, while the gull-wing termination ensures secure surface-mount attachment.
