GS4B033162CAT

GS4B033162CAT Description

The GS4B033162CAT 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 31.6KΩ 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 a low temperature coefficient (±25ppm/°C), maintaining stability across a wide operating range of -55°C to +125°C. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it is engineered for reliability in precision analog and digital systems.
