GUS-QS8A-02-4322-FA Description

The GUS-QS8A-02-4322-FA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated resistors, each with a 43.2kΩ resistance, 1% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable power handling in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while its 4.9mm x 6.02mm x 1.47mm footprint optimizes space efficiency.

GUS-QS8A-02-4322-FA Features

• High Precision: Thin-film technology ensures low TCR (±50ppm/°C) and tight tolerance (1%) for critical analog circuits.
• Robust Construction: QSOP package with 100V maximum voltage rating and 125°C max operating temperature for harsh environments.
• Isolated Design: 8 independent resistors (ISOL circuit designator) enable flexible circuit configurations.
• Space-Saving: Compact 4.9mm length and 1.47mm height ideal for high-density PCBs.
• Reliable Power Handling: 0.75W total dissipation (0.1W per resistor) balances performance and thermal management.
