GUS-QS0B-03-3652-FD Description

The GUS-QS0B-03-3652-FD 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 36.5KΩ resistance value, a tight 1% tolerance, and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in precision circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the compact 8.66mm × 6.02mm × 1.47mm footprint optimizes board space.
