GS4B034320JFT Description

The GS4B034320JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features a 432Ω resistance value with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring consistent performance in demanding circuits. Built with thin-film technology on a ceramic substrate, it delivers excellent stability with a low temperature coefficient of ±25ppm/°C. The SOIC-C series offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. Rated for 0.4W total power (0.05W per resistor) and 100V maximum voltage, it operates across a wide temperature range (-70°C to +125°C), making it suitable for harsh environments.
