GUS-QS8A-03-4222-GF Description

The GUS-QS8A-03-4222-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device features 8 isolated resistors, each with a 42.2KΩ resistance and a tight 2% tolerance. It operates within a wide temperature range of -70°C to +125°C, ensuring reliability in demanding environments. With a power rating of 0.75W (3/4W) total and 0.1W (1/10W) per resistor, it balances power handling and compactness. The ±25ppm/°C temperature coefficient enhances stability, while the 100V maximum voltage rating suits medium-voltage circuits. Packaged in a tube, this surface-mount component is ideal for automated assembly.

GUS-QS8A-03-4222-GF Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, reducing crosstalk.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with gull-wing leads for easy soldering.
• Robust Performance: Rated for 125°C maximum operating temperature and derated power up to 125°C.
• Low TCR (±25ppm/°C): Minimizes resistance drift across temperature fluctuations.
• Automotive-Grade Alternatives: While not automotive-qualified, its reliability makes it suitable for industrial and telecom applications.
