GUS-QS0B-02-8452-DA Description

The GUS-QS0B-02-8452-DA 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 84.5KΩ resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its gull-wing termination and 0.64mm terminal pitch ensure compatibility with automated PCB assembly processes. The rectangular QSOP case (8.66mm x 6.02mm x 1.47mm) provides a compact footprint, ideal for space-constrained designs.
