GS4B033830FDT Description

The GS4B033830FDT from TT Electronics/IRC is a high-precision 7-resistor thin-film network designed for surface-mount applications in demanding electronic circuits. Encased in a ceramic SOIC-8 package, it offers a 383Ω resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this network is ideal for precision analog/digital systems requiring minimal drift. Its gull-wing termination and 1.27mm pitch facilitate reliable PCB assembly, while the ceramic substrate enhances thermal performance.
