GUS-QS8A-02-8452-CA Description

The GUS-QS8A-02-8452-CA 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 terminations, this device offers an 84.5KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a -70°C to +125°C operating range. Its 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The isolated (ISOL) circuit design provides flexibility in configurations, while the thin-film technology ensures low noise and high reliability.
