GUS-QS8A-03-4642-FF Description

The GUS-QS8A-03-4642-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 46.4KΩ resistance value with a tight 1% 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 SMD termination, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained PCB designs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling with precision.

GUS-QS8A-03-4642-FF Features

• Thin-film technology: Delivers superior accuracy, stability, and low noise compared to thick-film alternatives.
• Isolated circuit design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• High power density: 0.1W per resistor (0.75W total) in a miniature QSOP package.
• Wide operating range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Robust construction: Gull-wing leads ensure reliable surface-mount attachment, while the tube packaging protects during handling and assembly.
• Non-automotive grade: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
