GUS-QS8A-02-5102-DA Description

The GUS-QS8A-02-5102-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated 51kΩ resistors with a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C, ensuring stable performance 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 power handling in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the 1.47mm low-profile height suits space-constrained applications.

GUS-QS8A-02-5102-DA Features

• Precision Thin Film Technology: Ensures low noise, high stability, and excellent TCR performance.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, ideal for signal isolation.
• High Power Density: 0.75W total dissipation in a compact 4.9mm x 6.02mm footprint.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation circuits.
• Robust Construction: QSOP package with gull-wing leads for mechanical durability and solderability.
• Non-Automotive Grade: Optimized for commercial and industrial use (PPAP not required).
