GUS-QS8A-02-3571-DA Description

The GUS-QS8A-02-3571-DA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. This QSOP-packaged device features a 3.57KΩ resistance value per resistor with an ultra-tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it excels in circuits requiring isolation (denoted by the ISOL circuit designator) and precision. The 16-pin gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS8A-02-3571-DA Features

• Thin Film Technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• High Power Density: 0.75W total dissipation in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Isolated Resistors: Independent resistors (non-bussed) for flexible circuit design.
• Robust Construction: QSOP package with gull-wing leads ensures mechanical durability and solderability.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).
• Non-Automotive Grade: Ideal for industrial and commercial applications where PPAP compliance is not required.
