GUS-QS8A-03-2871-FF Description

The GUS-QS8A-03-2871-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 SMD termination, this device offers a 2.87KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -55°C to +125°C operating range. Its isolated (ISOL) circuit design allows independent resistor functionality, making it ideal for complex circuit configurations. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it balances power handling with compact dimensions (4.9mm x 6.02mm x 1.47mm).
