GS4B0137R4GFT Description

The GS4B0137R4GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film technology. Encased in a ceramic substrate, it offers superior thermal stability with a ±100ppm/°C temperature coefficient and a 2% absolute tolerance (with ±1% ratio tolerance). Its 37.4Ω resistance value and 100V maximum voltage rating make it suitable for signal conditioning, voltage division, and bus termination in harsh environments. The 0.05W (1/20) power rating per resistor and 0.4W total power dissipation ensure reliability under continuous load, while the SOIC package (4.9mm × 5.99mm × 1.45mm) enables compact PCB layouts.
