GUS-QS0B-03-4750-FD Description

The GUS-QS0B-03-4750-FD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 475Ω resistance value per element with a tight 1% tolerance and a low ±25ppm/°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 terminals, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The thin-film technology provides superior accuracy, low noise, and long-term reliability compared to thick-film alternatives.
