GS4B016491FAT

GS4B016491FAT Description

The GS4B016491FAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 7 resistors in a BUS configuration, each with a 6.49KΩ resistance and a tight 1% tolerance, ensuring consistent performance in precision circuits. Encased in a ceramic SOIC package, this component offers excellent thermal stability and durability, with a maximum operating temperature of 125°C and a power rating of 0.4W (0.05W per resistor). Its thin-film technology provides low noise and high accuracy, while the ±100ppm/°C temperature coefficient ensures reliable operation across a wide 70°C to 125°C derated power range. The 8-pin gull-wing termination facilitates easy surface-mount (SMD) assembly, making it ideal for automated PCB production.
