GUS-QS0B-03-1581-FA Description

The GUS-QS0B-03-1581-FA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 1.58KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. With a 0.05W (1/20) power rating per resistor and a 1W total power rating, it delivers reliable operation under high-voltage conditions (up to 100V). The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while its compact dimensions (8.66mm × 6.02mm × 1.47mm) save board space.

GUS-QS0B-03-1581-FA Features
