GUS-QS8A-03-1401-GA Description

The GUS-QS8A-03-1401-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 1.4KΩ resistance value with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and is supplied in tube packaging for automated assembly. With a maximum operating voltage of 100V and a total power rating of 0.75W (0.1W per resistor), this component is ideal for high-density PCB designs requiring precision and durability.
