GUS-QS0B-02-1821-DA Description

The GUS-QS0B-02-1821-DA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 1.82KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. With a ±50ppm/°C temperature coefficient and a power rating of 1W (0.05W per resistor), it delivers stable performance across a wide temperature range of 70°C to 125°C. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.

GUS-QS0B-02-1821-DA Features
