GUS-QS8A-01-4871-JF Description

The GUS-QS8A-01-4871-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 4.87KΩ resistance value per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP package, it offers a compact 4.9mm x 6.02mm footprint with a 1.47mm profile, making it ideal for space-constrained designs. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 100V maximum voltage rating and 0.75W total power rating (0.1W per resistor) enhance durability in demanding circuits.

GUS-QS8A-01-4871-JF Features

• Thin-Film Technology: Delivers superior accuracy and low noise compared to thick-film alternatives.
• High Power Handling: 0.75W total power (3/4W) with derating up to 125°C, suitable for thermally challenging environments.
• Isolated Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive analog/digital circuits.
