GS4B015490CT Description

The GS4B015490CT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for demanding surface-mount applications. It features a 549Ω resistance value with an ultra-tight ±0.25% absolute tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The thin-film technology delivers superior accuracy and reliability, while the 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits. Its 100V maximum voltage rating and gull-wing termination ensure robust connectivity in compact designs.
