GS8A028872DT Description

The GS8A028872DT from TT Electronics/IRC is a high-precision 8-resistor network in a 16-pin narrow SOIC package, designed for isolated (ISOL) circuit applications. Built with ceramic substrate and thin-film technology, it offers excellent stability with a ±50ppm/°C temperature coefficient and a tight ±0.5% absolute tolerance. Each resistor features a 0.1W (1/10) power rating, totaling 0.8W for the network, and operates within a wide temperature range of 70°C to 125°C (derated). The 88.7KΩ resistance value and 100V maximum voltage rating make it suitable for precision analog and digital circuits.
