GUS-QS0B-03-3901-FA Description

The GUS-QS0B-03-3901-FA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for surface-mount applications requiring stable performance in compact designs. This 20-pin QSOP package integrates 19 resistors, each with a 3.9KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (70°C to 125°C). With a 1W total power rating (0.05W per resistor) and 100V maximum voltage rating, it delivers robust performance in space-constrained circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the rectangular QSOP case (8.66mm × 6.02mm × 1.47mm) optimizes board real estate.
