GUS-QS0B-03-9761-DA Description

The GUS-QS0B-03-9761-DA 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 9.76KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C). The network supports a maximum voltage rating of 100V and a total power dissipation of 1W (0.05W per resistor), making it suitable for high-reliability applications. Its gull-wing termination and compact dimensions (8.66mm x 6.02mm x 1.47mm) enable efficient PCB space utilization.
