GUS-QS0B-03-3242-FD Description

The GUS-QS0B-03-3242-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 32.4KΩ resistance value and a tight 1% tolerance, ensuring consistent performance in precision circuits. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of 70°C to 125°C, derated for optimal reliability. The network supports a maximum voltage rating of 100V and a total power rating of 1W (0.05W per resistor), making it suitable for compact, high-density designs. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the 1.47mm low-profile height maximizes space efficiency.
