GUS-QS0B-03-9531-GF Description

The GUS-QS0B-03-9531-GF 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 9.53KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in precision circuits. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating temperature range of 70°C to 125°C. The device supports a maximum voltage rating of 100V and offers a total power rating of 1W (0.05W per resistor), making it suitable for power-sensitive designs. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained layouts.

GUS-QS0B-03-9531-GF Features
