GS4B033161BBT Description

The GS4B033161BBT 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 3.16KΩ resistance per resistor with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). The network features gull-wing terminations with a 1.27mm pitch, optimized for automated PCB assembly. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it balances performance and reliability in demanding circuits. The non-automotive, non-PPAP compliant part is supplied in tubes, making it suitable for prototyping and low-to-medium volume production.
