GUS-QS8A-03-71R5-DD Description

The GUS-QS8A-03-71R5-DD from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull wing termination, this device offers a 71.5 Ω resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its isolated (ISOL) circuit design allows independent resistor operation, making it ideal for precision signal conditioning. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances performance and reliability in compact designs.
