GUS-QS8A-02-1783-JF Description

The GUS-QS8A-02-1783-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount circuits. This 16-pin QSOP package features 8 isolated resistors, each with a 178K Ohm resistance, 5% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70 to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports moderate power dissipation while maintaining reliability. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, making it ideal for compact designs.

GUS-QS8A-02-1783-JF Features

• Thin-Film Technology: Delivers high accuracy and low noise for sensitive analog/digital circuits.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, enhancing design flexibility.
• Robust Power Handling: 0.75W total power (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint, optimized for space-constrained PCBs.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.
• Stable TCR: ±50ppm/°C ensures minimal resistance drift under thermal stress.
