GUS-QS0B-03-9100-DB Description

The GUS-QS0B-03-9100-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors with a 910Ω resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it ensures reliable performance in compact, high-density circuits. The gull-wing termination facilitates easy soldering, while the QSOP case (8.66mm x 6.02mm x 1.47mm) optimizes board space. Rated for -70°C to +125°C, it suits industrial and instrumentation environments where stability and precision are critical.
