GS4B031432FFT

GS4B031432FFT Description

The GS4B031432FFT 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. Constructed 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 14.3KΩ resistance value per resistor, rated for 0.05W (1/20) power dissipation per element and 0.4W total power. Its 100V maximum voltage rating and 125°C operating temperature range ensure reliability in harsh environments. The SOIC-C series package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations (1.27mm pitch) facilitates automated assembly.
