GS4B035490JFT Description

The GS4B035490JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features a 549Ω resistance value with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring reliable signal integrity. The thin-film technology and ceramic case style provide excellent stability, with a low temperature coefficient of ±25ppm/°C across an operating range of 70°C to 125°C. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ±0.1mm height/length tolerances ensure consistent placement.
