GS4B021331CAT Description

The GS4B021331CAT from TT Electronics/IRC is a high-precision 7-resistor bussed network housed in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for surface-mount applications, it features a 1.33KΩ resistance value with an absolute tolerance of ±0.25% and a ratio tolerance of ±0.05%, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The thin-film technology delivers stable performance with a low temperature coefficient of ±50ppm/°C, making it suitable for environments with operating temperatures ranging from 70°C to 125°C. With a power rating of 0.4W (0.05W per resistor) and a maximum voltage rating of 100V, this network is engineered for reliability in precision analog and digital systems.
