GUS-QS8A-03-1331-DA Description

The GUS-QS8A-03-1331-DA 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 1.33KΩ resistance and a tight 0.5% 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 and 100V maximum voltage rating provide robust handling of moderate power loads, while the gull-wing termination ensures reliable solderability in automated PCB assembly.

GUS-QS8A-03-1331-DA Features

• Precision Thin Film Technology: Offers low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Isolated Resistors (ISOL): Eight independent 1.33KΩ resistors enable flexible circuit design without crosstalk.
• High Power Handling: 0.1W per resistor (0.75W total) outperforms similar networks in power density.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, derated for high-temperature environments.
• Automated Assembly Optimized: 0.64mm terminal pitch and gull-wing leads ensure compatibility with pick-and-place systems.
