GQ8A031800GCT Description

The GQ8A031800GCT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance and low thermal drift. Housed in a 16-pin QSOP ceramic package, it features 180Ω resistance per element with a tight 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in demanding environments. Its 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for distributed power dissipation. The 100V maximum voltage rating and gull-wing SMD termination facilitate robust surface-mount integration. Packaged in a tube, it is ideal for automated assembly processes.
