GS4B037871FT Description

The GS4B037871FT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for surface-mount applications, it features a 7.87KΩ resistance per element with a tight ±1% absolute tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The thin-film technology provides excellent accuracy and reliability, while the ceramic case enhances thermal and mechanical durability. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits.
