GUS-QS0B-03-5111-FD Description

The GUS-QS0B-03-5111-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 5.11KΩ 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 temperature range of 70°C to 125°C. The device features a 1W total power rating (0.05W per resistor) and supports a maximum voltage rating of 100V, making it suitable for high-reliability applications. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the compact 8.66mm x 6.02mm x 1.47mm footprint optimizes board space.
