GUS-QS0B-02-1201-DD Description

The GUS-QS0B-02-1201-DD 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 1.2KΩ resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of 70°C to 125°C. The device is rated for 1W total power dissipation (0.05W per resistor) and supports a maximum voltage of 100V, making it suitable for precision analog and digital systems. Its gull-wing termination and compact dimensions (8.66mm x 6.02mm x 1.47mm) facilitate easy integration into space-constrained PCB layouts.
