GUS-QS8A-03-2942-CA Description

The GUS-QS8A-03-2942-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 a 29.4KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. The isolated (ISOL) circuit design provides flexibility in signal routing, while the thin-film technology guarantees low noise and high accuracy.

GUS-QS8A-03-2942-CA Features
