GUS-QS0B-03-2101-J Description

The GUS-QS0B-03-2101-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 2.1KΩ resistance value and a 5% tolerance, delivering a total power rating of 1W (0.05W per resistor). It operates within a wide temperature range of 70°C to 125°C (derated) and features a low temperature coefficient of ±25ppm/°C, ensuring stability under thermal stress. The gull-wing termination and 0.64mm terminal pitch make it ideal for surface-mount (SMD) PCB designs, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.
