GS4B028660BT Description

The GS4B028660BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC (SOIC-C Series) device integrates 7 bussed resistors with a 866Ω resistance value and an ultra-tight ±0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Built with thin-film technology, it offers a low ±50ppm/°C temperature coefficient, maintaining stable performance across a wide temperature range (70°C to 125°C). The ceramic case provides robust thermal and mechanical stability, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a maximum voltage rating of 100V and a total power rating of 0.4W (0.05W per resistor), this network is ideal for precision analog and digital systems.
