GUS-QS8B-03-3920-B Description

The GUS-QS8B-03-3920-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 392Ω resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.
