GS4B028660CAT

GS4B028660CAT Description

The GS4B028660CAT 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 ceramic substrate and thin-film technology, it delivers exceptional stability with a ±50ppm/°C temperature coefficient and ±0.25% absolute tolerance. The network operates across a 70°C to 125°C derated power range, with a maximum voltage rating of 100V and 0.4W total power dissipation. Its 866Ω resistance value and 0.05W per resistor rating make it ideal for precision analog and digital circuits. The gull-wing termination and 1.27mm terminal pitch ensure reliable PCB integration.
