GS8A031101GFT Description

The GS8A031101GFT from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications. Packaged in a 16-pin narrow SOIC (SOIC-C) with a ceramic substrate, it offers superior thermal stability and reliability. Each resistor features a 1.1KΩ value with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in matched circuits. The thin-film technology delivers a low ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. Rated for 0.1W per resistor (0.8W total) and 100V maximum voltage, it operates across a -70°C to +125°C range, with derated power up to 125°C. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
