GUS-QS0B-02-1242-DB Description

The GUS-QS0B-02-1242-DB 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 12.4KΩ resistance value and a 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 network supports a maximum voltage rating of 100V and offers a total power rating 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) facilitate easy integration into space-constrained PCB layouts.
