GUS-QS8A-02-1691-CB Description

The GUS-QS8A-02-1691-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 1.69 kΩ resistance and an exceptional ±0.25% tolerance. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates across a wide temperature range of -70°C to +125°C, with a low ±50ppm/°C temperature coefficient for stable performance. The 100V maximum voltage rating and gull-wing termination ensure reliable connectivity in compact PCB layouts. Packaged in a tube, this RoHS-non-compliant component is ideal for precision analog and digital circuits.
