GUS-QS8B-01-7320-D Description

The GUS-QS8B-01-7320-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, each with a 732Ω resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. With a ±100ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range of 70°C to 125°C. The network supports a maximum voltage rating of 100V and offers a total power rating of 0.75W (3/4W), distributed as 0.05W (1/20W) per resistor. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes space efficiency.
