GUS-QS8B-03-4640-B Description

The GUS-QS8B-03-4640-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors with a 464 Ω resistance value, offering a tight tolerance of ±0.1% and a low temperature coefficient of ±25 ppm/°C. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it operates reliably across a -70°C to +125°C temperature range. The gull-wing termination ensures secure PCB mounting, while the 100V maximum voltage rating makes it suitable for high-voltage circuits. Its compact dimensions (4.9mm x 6.02mm x 1.47mm) and ±0.1mm length/height tolerances ensure consistent performance in space-constrained designs.
