GUS-QS8A-03-1651-JF Description

The GUS-QS8A-03-1651-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 1.65KΩ resistance, 5% tolerance, and a ±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 -55°C to +125°C, derated from 70°C to 125°C. The gull-wing termination and 0.64mm terminal pitch ensure easy PCB integration, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
