GUS-QS8A-02-1211-FA Description

The GUS-QS8A-02-1211-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 8 isolated resistors, each with a 1.21KΩ resistance, 1% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stability 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 delivers reliable performance in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the 1.47mm low-profile height suits space-constrained applications.
