GUS-QS0B-03-4120-DD Description

The GUS-QS0B-03-4120-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 412Ω resistance value and an ultra-tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C derated, 125°C max). The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for compact, high-density PCB designs. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in automated assembly processes.
