GS4B0127R0JFT Description

The GS4B0127R0JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 27Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring consistent performance in matched circuits. The thin-film technology delivers a low temperature coefficient of ±100ppm/°C, maintaining stability across a wide operating range of -55°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 demanding environments. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
