GUS-QS8B-02-3571-J Description

The GUS-QS8B-02-3571-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 3.57KΩ resistance value and a tight 5% tolerance. It operates within a wide temperature range of 70°C to 125°C (derated) and features a ±50ppm/°C temperature coefficient, ensuring stability under thermal stress. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, this surface-mount (SMD) network is ideal for compact, high-density PCB designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering, while its 1.47mm low profile (1.63mm seated height) suits space-constrained applications. Packaged in a tube, it ensures safe handling and storage.

GUS-QS8B-02-3571-J Features
