GS8A0191R0DDT

GS8A0191R0DDT Description

The GS8A0191R0DDT from TT Electronics/IRC is a high-precision 8-resistor network in a 16-pin narrow SOIC package, designed for isolated circuit applications (ISOL). Built with thin-film technology on a ceramic substrate, it delivers excellent stability with a ±100ppm/°C temperature coefficient and ±0.5% absolute tolerance. Each resistor offers 91Ω resistance at 0.1W (1/10W) power rating per element, totaling 0.8W for the network. The SOIC-C series package features gull-wing terminations with a 1.27mm pitch, ensuring reliable surface-mount (SMD) compatibility. Its rectangular ceramic case provides superior thermal performance, supporting operation from 70°C to 125°C at derated power, with a maximum voltage rating of 100V. Non-compliant with EU RoHS, it is suited for industrial and non-automotive applications.
