GUS-QS0B-03-2201-DB Description

The GUS-QS0B-03-2201-DB 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 2.2KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C derated, 125°C max operating). The network supports a maximum voltage rating of 100V and offers a total power rating of 1W (0.05W per resistor), making it suitable for power-sensitive applications. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained environments.
