GUS-QS8A-01-1271-GA Description

The GUS-QS8A-01-1271-GA 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 features 8 isolated resistors, each with a 1.27KΩ resistance value and a tight 2% tolerance. With a power rating of 0.75W (3/4W) and a ±100ppm/°C temperature coefficient, it ensures stable operation across a wide temperature range of 70°C to 125°C. The gull-wing termination and surface-mount design make it ideal for automated PCB assembly, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) save board space.
