GUS-QS0B-03-9761-FD Description

The GUS-QS0B-03-9761-FD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 9.76KΩ resistance value and a tight 1% tolerance. It operates over a wide temperature range of 70°C to 125°C (derated) and delivers a total power rating of 1W (0.05W per resistor). The network features a ±25ppm/°C temperature coefficient, ensuring stability in demanding environments. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 8.66mm x 6.02mm x 1.47mm footprint suits space-constrained designs.
