GUS-QS8B-03-3401-C Description

The GUS-QS8B-03-3401-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 3.4KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS8B-03-3401-C Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length).
• High Power Density: 0.75W total dissipation in a miniature footprint, ideal for densely populated boards.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power at elevated temperatures.
• Automotive-Grade Alternatives: While not PPAP or Automotive certified, its performance parallels automotive-grade components in non-safety-critical roles.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded soldering.
