GUS-QS8A-02-4871-CA Description

The GUS-QS8A-02-4871-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated resistors, each with a 4.87KΩ resistance, a tight ±0.25% tolerance, and a low ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for precision analog and digital circuits. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the compact 4.9mm x 6.02mm footprint and 1.47mm profile optimize space efficiency in dense PCB layouts.
