GUS-QS0B-02-1781-B Description

The GUS-QS0B-02-1781-B 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 1.78KΩ resistance value, offering a tight tolerance of ±0.1% 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, making it suitable for harsh environments. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the compact 8.66mm × 6.02mm × 1.47mm footprint optimizes board space.
