GUS-QS0B-03-9312-FD Description

The GUS-QS0B-03-9312-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 93.1kΩ 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 temperature range (70°C to 125°C derated, 125°C max). The network supports a 1W total power rating (0.05W per resistor) and operates at up to 100V, making it suitable for high-reliability designs. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.
