GS4B031911JGT Description

The GS4B031911JGT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features a 1.91KΩ resistance value with an absolute tolerance of ±5% and a ratio tolerance of ±2%. The device operates over a wide temperature range of -70°C to +125°C, with a thin-film technology ensuring low temperature coefficient (±25ppm/°C) and stable performance under thermal stress. Rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation, it supports 100V maximum voltage, making it suitable for demanding circuits.
