GS4B025491JFT Description

The GS4B025491JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) package. Designed for precision applications, it features a 5.49KΩ resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%. The device employs thin-film technology on a ceramic substrate, ensuring stability and reliability across a wide temperature range of -70°C to +125°C. With a power rating of 0.4W (0.05W per resistor) and a maximum voltage rating of 100V, it is engineered for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ±50ppm/°C temperature coefficient guarantees minimal drift under thermal stress.
