GUS-QS0B-02-1691-CC Description

The GUS-QS0B-02-1691-CC 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 1.69KΩ resistance value, offering a tight tolerance of ±0.25% 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. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the compact 8.66mm × 6.02mm × 1.47mm footprint suits space-constrained designs.
