GUS-QS8A-02-1690-FD Description

The GUS-QS8A-02-1690-FD from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP (Quarter Small Outline Package), this surface-mount device (SMD) offers a compact footprint (4.9mm × 6.02mm × 1.47mm) with gull-wing terminations for reliable PCB mounting. Each resistor in the network features a 169Ω resistance value with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding environments.
