GUS-QS0B-03-1331-CC Description

The GUS-QS0B-03-1331-CC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 1.33KΩ resistance value per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and supports 100V maximum voltage. Its thin-film technology provides superior accuracy, low noise, and long-term reliability compared to thick-film alternatives.
