GS8A031781GAT

GS8A031781GAT Description

The GS8A031781GAT from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications. Housed in a 16-pin narrow SOIC ceramic package, it features thin-film technology with a 1.78KΩ resistance value and a tight ±2% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a ±25ppm/°C temperature coefficient, ensuring stability in demanding environments. Its 0.1W power rating per resistor (0.8W total) and 100V maximum voltage rating make it suitable for high-reliability circuits. The SOIC-C series construction offers superior thermal and mechanical performance compared to standard plastic packages.
