GUS-QS8A-03-8450-FF Description

The GUS-QS8A-03-8450-FF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP package with gull-wing surface-mount termination, this device offers an isolated (ISOL) circuit configuration, ensuring individual resistor performance without shared connections. With a resistance value of 845Ω, a tight 1% tolerance, and a low ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide temperature range (70°C to 125°C). The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Its compact dimensions (4.9mm length × 6.02mm depth × 1.47mm height) and 0.64mm terminal pitch enable high-density PCB layouts.
