GS4B025490JT

GS4B025490JT Description

The GS4B025490JT 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 resistance values under varying thermal conditions. Encased in a ceramic (SOIC-C series) substrate, it offers superior thermal management and durability. With a 549Ω resistance per element (±5% tolerance) and a ±50ppm/°C temperature coefficient, this thin-film resistor network ensures reliable performance across a 70°C to 125°C operating range. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for moderate-power circuits. The gull-wing termination and 1.27mm pitch facilitate easy surface-mount assembly, while its compact dimensions (4.9mm × 5.99mm × 1.45mm) save board space.
