GUS-QS8A-02-4120-DB Description

The GUS-QS8A-02-4120-DB 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 412Ω resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°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 and 100V maximum voltage rating provide robust handling of moderate power loads, while the gull-wing termination ensures reliable solderability for automated PCB assembly.

GUS-QS8A-02-4120-DB Features

• Precision Thin Film Technology: Offers low noise and high stability for sensitive analog circuits.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, reducing crosstalk in multi-channel systems.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
• High Power Density: 0.1W per resistor (0.75W total) in a miniature footprint, outperforming similar arrays in power dissipation.
• Automation-Friendly: Tube packaging and 0.64mm terminal pitch streamline pick-and-place processes.
• Wide Temperature Range: Reliable operation from -70°C to +125°C, even at derated power.
