GUS-QS8A-03-1051-FB Description

The GUS-QS8A-03-1051-FB 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 1.05KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The isolated (ISOL) circuit design provides flexibility in signal conditioning, voltage division, and impedance matching applications.
