GUS-QS8A-02-6650-DA Description

The GUS-QS8A-02-6650-DA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a 665Ω resistance value per resistor and a tight 0.5% tolerance, this component ensures reliable signal conditioning, voltage division, and impedance matching in compact circuits. Housed in a 16-pin QSOP package, it features gull-wing terminations for secure PCB mounting and offers a 0.75W (3/4W) total power rating, derated for operation up to 125°C. Its ±50ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for stable performance in industrial and instrumentation environments.

GUS-QS8A-02-6650-DA Features

• Precision Thin Film Technology: Delivers low noise and high stability (±50ppm/°C) for sensitive analog circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with ±0.1mm dimensional tolerances, ideal for space-constrained designs.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, enhancing design flexibility.
• Robust Power Handling: 0.1W per resistor (0.75W total) with derated performance up to 125°C.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its reliability suits industrial, medical, and test equipment.
