GS4B023480JFT Description

The GS4B023480JFT 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 resistance. With a 348Ω resistance value and ±5% absolute tolerance, it delivers consistent performance in compact circuits. The ceramic-based construction ensures durability, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift across its operating range of -70°C to +125°C. Rated for 100V maximum voltage and 0.4W total power dissipation, it combines reliability with space efficiency. The gull-wing termination and 1.27mm terminal pitch facilitate easy surface-mount assembly.
