GUS-QS0B-02-4121-B Description

The GUS-QS0B-02-4121-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 4.12KΩ resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°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 suitable for high-density PCB designs. The thin-film technology provides superior accuracy, low noise, and long-term reliability compared to thick-film alternatives.
