GUS-QS8A-03-1802-JF Description

The GUS-QS8A-03-1802-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated 18K Ohm resistors with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable operation across a wide temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, it offers robust power handling in a compact 4.9mm x 6.02mm x 1.47mm surface-mount package. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB assembly, while the 100V maximum voltage rating enhances durability in high-voltage environments.

GUS-QS8A-03-1802-JF Features

• High Precision: Thin-film technology delivers ±25ppm/°C thermal stability and 5% resistance tolerance for consistent performance.
• Compact & Durable: QSOP-16 package with a 1.63mm seated height optimizes space in dense PCB layouts.
• Isolated Resistors: 8 independent 18K Ohm resistors (ISOL designator) prevent cross-talk in multi-channel circuits.
• Wide Operating Range: Rated for -70°C to +125°C, suitable for industrial and automotive derating conditions (though not PPAP/Automotive certified).
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) exceeds typical network array ratings.
• Surface-Mount Ready: Gull-wing leads and 0.64mm pitch ensure compatibility with automated assembly processes.
