GUS-QS8A-03-1052-FA Description

The GUS-QS8A-03-1052-FA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features eight isolated 10.5KΩ resistors with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it offers robust power handling in a compact 4.9mm × 6.02mm × 1.47mm footprint. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB assembly, while the tube packaging ensures safe handling and storage.

GUS-QS8A-03-1052-FA Features
