GS4A029101DAT

GS4A029101DAT Description

The GS4A029101DAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 9.1 kΩ and an absolute tolerance of ±0.5%. The network operates over a wide temperature range of 70°C to 125°C with a derated power rating, ensuring reliable performance in thermally challenging environments. Its ±50 ppm/°C temperature coefficient and ±0.05% ratio tolerance make it ideal for precision analog and signal conditioning circuits. The SOIC-C series construction provides excellent stability and low noise, while the gull-wing termination ensures compatibility with standard surface-mount assembly processes.
