GUS-QS0B-02-1961-DA Description

The GUS-QS0B-02-1961-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 1.96KΩ resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C. The gull-wing termination ensures secure PCB mounting, while the compact 8.66mm x 6.02mm x 1.47mm footprint suits space-constrained designs.
