GUS-QS8A-02-1473-JF Description

The GUS-QS8A-02-1473-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 surface-mount device features 8 isolated resistors, each with a 147K Ohm resistance and a 5% tolerance, ensuring reliable signal integrity and stable performance. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates efficiently across a wide temperature range of 70°C to 125°C, derated for optimal thermal management. The ±50ppm/°C temperature coefficient minimizes resistance drift, making it ideal for environments with fluctuating temperatures. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the compact 4.9mm x 6.02mm x 1.47mm footprint suits space-constrained designs.

GUS-QS8A-02-1473-JF Features

• Isolated Resistor Network: 8 independent 147K Ohm resistors with 100V maximum voltage rating, ensuring signal isolation and reduced crosstalk.
• Thin-Film Technology: Delivers superior stability, low noise, and tight tolerance (±5%) for precision applications.
• Robust Thermal Performance: Operates up to 125°C with derated power handling, backed by a ±50ppm/°C TCR.
