GS4B039091FT Description

The GS4B039091FT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 9.09KΩ resistance value with a tight ±1% tolerance, this thin-film ceramic-based network ensures stable performance across a wide temperature range (70°C to 125°C). Its ±25ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision circuits. The SOIC-C series construction offers 0.05W (1/20) power rating per resistor (0.4W total) and a 100V maximum voltage rating, housed in a compact 4.9mm × 5.99mm × 1.45mm ceramic package with gull-wing terminations for reliable PCB mounting.
