GS4B0290R9JFT Description

The GS4B0290R9JFT 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. With a 90.9Ω resistance per element and ±5% absolute tolerance, this ceramic-based network ensures reliable performance in demanding environments. Its ±50ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for thermally challenging circuits. The SOIC-C series construction provides robust mechanical stability, while the gull-wing termination enables secure surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation, it balances compact dimensions (4.9mm × 5.99mm × 1.45mm) with high power density.
