GUS-QS8A-03-3921-CA Description

The GUS-QS8A-03-3921-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 3.92KΩ resistance, a tight ±0.25% tolerance, and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it delivers reliable performance in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its 1.47mm profile suits space-constrained layouts.
