GUS-QS8A-02-8451-FA Description

The GUS-QS8A-02-8451-FA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a resistance value of 8.45KΩ and a tight 1% tolerance, this component ensures reliable performance in precision circuits. The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for applications requiring individual signal paths. Encased in a 16-pin QSOP package, it features a compact footprint (4.9mm × 6.02mm × 1.47mm) with gull-wing terminations for robust PCB mounting. Rated for 0.75W total power dissipation (0.1W per resistor), it operates across a wide temperature range (-55°C to +125°C) with a low ±50ppm/°C temperature coefficient, ensuring stability in harsh environments.

GUS-QS8A-02-8451-FA Features

• Thin Film Technology: Delivers superior accuracy and low noise compared to thick-film alternatives.
• High Power Handling: 0.75W total power rating (3/4W) with derating up to 125°C.
• Isolated Design: Each of the 8 resistors operates independently, eliminating crosstalk.
