GUS-QS8A-03-1053-CA Description

The GUS-QS8A-03-1053-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated resistors, each with a 105KΩ resistance, a tight 0.25% tolerance, and an ultra-stable ±25ppm/°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 PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes space efficiency.
