GS8A028661FT Description

The GS8A028661FT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for isolation (ISOL) applications. Housed in a 16-pin SOIC ceramic package, it offers an 8.66KΩ resistance per resistor with a tight 1% tolerance and low ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. With a 0.8W total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount (SMD) network is engineered for reliability in demanding circuits. Its gull-wing termination and ±0.1mm dimensional tolerances facilitate precise PCB assembly, while the ceramic case enhances thermal and mechanical robustness.
