GUS-QS8A-03-1822-GG Description

The GUS-QS8A-03-1822-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 8-resistor isolated network features a 18.2K Ohm resistance value per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP package with gull-wing termination, it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is engineered for reliability in demanding circuits.

GUS-QS8A-03-1822-GG Features

• Thin-film technology: Delivers superior accuracy, low noise, and excellent long-term stability.
• Isolated circuit design (ISOL): Each resistor operates independently, enhancing flexibility in circuit design.
• High power density: 0.75W total power in a compact QSOP package outperforms similar networks in thermal management.
• Wide operating range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Robust construction: Gull-wing leads ensure secure surface mounting, while the tube packaging protects during handling and assembly.
• Non-automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance isn’t required.
