GUS-QS8A-02-7681-JA Description

The GUS-QS8A-02-7681-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 7.68KΩ resistance value and a 5% tolerance. With a power rating of 0.75W (3/4W) total and 0.1W (1/10W) per resistor, it operates reliably across a temperature range of 70°C to 125°C (derated) and up to 125°C maximum. The ±50ppm/°C temperature coefficient ensures stable performance in varying thermal conditions. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
