GUS-QS8A-03-56R2-FD Description

The GUS-QS8A-03-56R2-FD 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 56.2 Ω resistance value and a tight 1% 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 for optimal performance. The device offers excellent stability with a low temperature coefficient of ±25ppm/°C and a maximum voltage rating of 100V. Its gull-wing termination ensures secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.
