GUS-QS0B-03-6980-DA Description

The GUS-QS0B-03-6980-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter-Small Outline Package) device integrates 19 resistors with a 698Ω resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°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, making it suitable for environments with thermal stress. The gull-wing termination ensures secure surface-mount (SMD) assembly, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save PCB space. Packaged in a protective tube, this non-automotive and non-PPAP compliant component is ideal for precision analog and digital circuits.
