GUS-QS8A-03-4991-CA Description

The GUS-QS8A-03-4991-CA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull wing terminations, this component offers a 4.99KΩ resistance per element with an exceptional ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its isolated (ISOL) circuit design allows independent resistor functionality, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for power-sensitive designs. The 100V maximum voltage rating and thin film technology provide superior reliability in precision analog and digital circuits.
