GUS-QS8A-03-1913-FF Description

The GUS-QS8A-03-1913-FF by 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 191K Ohm network offers 1% tolerance and a ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. 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 enhances flexibility in signal conditioning, voltage division, and impedance matching applications.
