GS4B036490JDT Description

The GS4B036490JDT is a high-performance 7-resistor bussed network from TT Electronics/IRC, designed for precision applications in demanding electronic circuits. Encased in a narrow SOIC (Small Outline Integrated Circuit) ceramic package, this thin-film resistor network offers a 649Ω resistance per element with a tight ±5% absolute tolerance and an exceptional ±0.5% ratio tolerance. Its ±25ppm/°C temperature coefficient ensures minimal resistance drift across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 8-pin gull-wing termination facilitates reliable surface-mount (SMD) assembly, while the 0.05W (1/20W) power rating per resistor and 0.4W total power dissipation balance compactness with robustness.
