GUS-QS8A-03-2740-CA Description

The GUS-QS8A-03-2740-CA from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull-wing terminations, this device offers a 274Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a -70°C to +125°C operating range. Its isolated (ISOL) circuit design allows independent resistor operation, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power handling make it suitable for power-sensitive designs. The compact 4.9mm × 6.02mm × 1.47mm footprint and 0.64mm terminal pitch enable high-density PCB layouts.
