GUS-QS8B-02-1581-D Description

The GUS-QS8B-02-1581-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors with a 1.58KΩ resistance value, offering a tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it operates reliably across a 70°C to 125°C derated power range, peaking at 125°C maximum operating temperature. The gull-wing termination and 0.64mm terminal pitch ensure secure PCB mounting, while its compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.
