GS4B021781FBT Description

The GS4B021781FBT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC package, designed for BUS circuit applications. It features a 1.78KΩ resistance value per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the 0.4W total power rating (0.05W per resistor) supports moderate power dissipation. With a 100V maximum voltage rating and ±0.1mm dimensional tolerances, this network is engineered for precision and durability in compact PCB designs.
