GS4B0126R1GFT Description

The GS4B0126R1GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C Series) package. Designed for precision applications, it features a 26.1Ω resistance per element with an absolute tolerance of ±2% and a ratio tolerance of ±1%, ensuring consistent performance in matched-resistor circuits. The thin-film technology and ceramic case provide excellent stability, with a temperature coefficient of ±100ppm/°C, 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 reliably within a temperature range of 70°C to 125°C and withstands voltages up to 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
