GS4B032940JFT Description

The GS4B032940JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 294Ω resistance value per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%. Its thin-film technology ensures stable performance, supported by a low temperature coefficient of ±25ppm/°C, making it suitable for environments with operating temperatures ranging from 70°C to 125°C. The network is rated for 0.05W (1/20W) power dissipation per resistor and a total power rating of 0.4W, with a maximum voltage rating of 100V. The gull-wing termination and surface-mount design facilitate easy PCB integration.
