GS4B0126R7JFT Description

The GS4B0126R7JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network housed in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision and reliability, it features a 26.7Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring consistent performance in critical circuits. The thin-film technology delivers excellent stability with a ±100ppm/°C temperature coefficient, making it suitable for environments with fluctuating thermal conditions. Rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation, it operates within a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
