GUS-QS0B-02-2800-DC Description

The GUS-QS0B-02-2800-DC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 280Ω resistance value per resistor with an ultra-tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it ideal for precision analog and digital circuits. The 6.02mm × 8.66mm footprint and 1.47mm profile enable high-density PCB designs.
