GUS-QS0B-03-5111-GF Description

The GUS-QS0B-03-5111-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 5.11KΩ resistance value and a tight 2% tolerance. It operates over a wide temperature range of -70°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in demanding environments. The network delivers a total power rating of 1W (0.05W per resistor) and features a low ±25ppm/°C temperature coefficient, minimizing resistance drift. Its gull-wing termination and surface-mount design make it ideal for automated assembly processes.
