GS4B024121DT

GS4B024121DT Description

The GS4B024121DT 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 4.12KΩ resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, this ceramic-based thin-film network ensures stable performance across a wide operating temperature range of 70°C to 125°C. Its SOIC-C series construction offers robust 0.4W total power handling (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The gull-wing termination and 1.27mm pitch facilitate reliable PCB mounting, while the compact 4.9mm x 5.99mm x 1.45mm footprint optimizes space efficiency.
