GUS-QS0B-03-1741-JA Description

The GUS-QS0B-03-1741-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 1.74KΩ resistance (5% tolerance) and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.
