GUS-QS0B-03-2741-DD Description

The GUS-QS0B-03-2741-DD 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 2.74KΩ 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 of 70°C to 125°C. The network supports a maximum operating temperature of 125°C and a derated power rating of 0.05W (1/20W) per resistor, totaling 1W for the entire array. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 8.66mm x 6.02mm x 1.47mm footprint suits space-constrained designs.
