GUS-QS8B-03-1371-GF Description

The GUS-QS8B-03-1371-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 1.37KΩ resistance value, a tight 2% tolerance, and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, it balances power handling with compact dimensions (4.9mm x 6.02mm x 1.47mm). The gull-wing termination facilitates reliable SMT soldering, while the tube packaging ensures safe handling and storage.
