GS4B031212FFT

GS4B031212FFT Description

The GS4B031212FFT 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. Built with ceramic substrate and thin-film technology, it delivers exceptional stability with a ±25ppm/°C temperature coefficient and ±1% absolute tolerance. The network features a 12.1KΩ resistance value per resistor, rated for 0.05W (1/20W) power dissipation per element and 0.4W total power. Its 100V maximum voltage rating and 125°C maximum operating temperature make it suitable for industrial and commercial environments. The gull-wing termination ensures reliable solder joints, while the SOIC package (4.9mm x 5.99mm x 1.45mm) offers compact PCB integration.
