GS4B031872CAT Description

The GS4B031872CAT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for demanding applications, it features a thin-film technology construction with a 0.25% absolute tolerance and an ultra-tight ±0.05% ratio tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a resistance value of 18.7KΩ and a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C). The 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for low-power, high-reliability designs.
