GUS-QS8A-03-3321-BB Description

The GUS-QS8A-03-3321-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 3.32KΩ resistance, offering a tight tolerance of ±0.1% and a low temperature coefficient of ±25ppm/°C. With a derated power range of 70°C to 125°C and a maximum operating temperature of 125°C, it ensures stable performance in thermally challenging environments. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating, combined with a 100V maximum voltage rating, make it suitable for precision analog and digital circuits.

GUS-QS8A-03-3321-BB Features

• High Precision: ±0.1% tolerance and ±25ppm/°C TCR ensure minimal drift.
• Robust Construction: Thin-film technology provides superior stability and low noise.
• Compact Design: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) QSOP package with 0.64mm terminal pitch for high-density PCB layouts.
• Isolated Resistors: Independent resistors (ISOL configuration) enhance signal integrity.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive-grade applications (though not PPAP or Automotive certified).
• Gull Wing Termination: Ensures reliable surface-mount soldering.
