GUS-QS8A-03-1541-DB Description

The GUS-QS8A-03-1541-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 1.54KΩ resistance, 0.5% tolerance, and a ±25ppm/°C temperature coefficient, ensuring exceptional stability across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable performance in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while its 1.47mm low profile suits space-constrained layouts.

GUS-QS8A-03-1541-DB Features

• Precision Thin Film Technology: Offers low noise and high accuracy (±0.5%) for critical analog circuits.
• Isolated Resistors (ISOL): Independent resistors minimize crosstalk, ideal for signal isolation.
• High Power Handling: 0.75W total (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: 4.9mm x 6.02mm footprint and 1.63mm seated height for dense PCB layouts.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.
• Non-Automotive/Non-PPAP: Optimized for commercial and industrial use where PPAP compliance isn’t required.
