GS4B038250CBT Description

The GS4B038250CBT from TT Electronics/IRC is a high-precision 7-resistor thin-film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers a 825Ω resistance per element with an exceptional ±0.25% 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 component is ideal for precision analog and digital circuits requiring tight tolerance and minimal drift. Its gull-wing termination and 1.27mm pitch facilitate reliable PCB assembly, while the ceramic substrate enhances thermal performance.
