GUS-QS8A-03-1782-JB Description

The GUS-QS8A-03-1782-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features eight isolated 17.8KΩ resistors with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide 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 is engineered for reliability in demanding circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.

GUS-QS8A-03-1782-JB Features

• Thin-film technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Isolated resistors (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel signal conditioning.
• High power handling: 0.75W total dissipation (0.1W per resistor) at 125°C derated power.
• Low TCR (±25ppm/°C): Minimizes resistance drift in varying thermal environments.
• QSOP package: Robust rectangular form factor with 1.63mm seated height for dense PCB layouts.
• Non-automotive grade: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
