GS4B035490GFT Description

The GS4B035490GFT 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 resistance. With a 549Ω resistance value and ±2% absolute tolerance, this ceramic-based network ensures reliable performance in demanding environments. Its ±25ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor (0.4W total) make it suitable for circuits requiring low drift and consistent power dissipation. The SOIC-C series construction features gull-wing terminations for secure surface-mount assembly, while its 100V maximum voltage rating and 125°C operating range ensure durability in industrial and commercial electronics.
