GUS-QS0B-03-4992-DB Description

The GUS-QS0B-03-4992-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 49.9KΩ resistance value, offering a tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C derated power range, peaking at 125°C maximum operating temperature. Its gull-wing termination and 0.64mm terminal pitch ensure secure PCB mounting, while the compact 8.66mm × 6.02mm × 1.47mm footprint suits space-constrained designs. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for precision analog and digital circuits.
