GS4B034990CBT Description

The GS4B034990CBT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC package, designed for surface-mount applications. With a 499Ω resistance per element, it delivers 0.25% tolerance and a ±25ppm/°C temperature coefficient, ensuring stability in demanding environments. The ceramic case and gull-wing termination provide robust mechanical and thermal performance, while the 0.4W total power rating (0.05W per resistor) supports reliable operation up to 125°C. Its BUS circuit designator makes it ideal for signal distribution in compact PCB layouts.
